Part of Epic 1: Foundation & Core Systems (Phase 1.1-1.2)
The previous URL-encoded SVG had unencoded quotes that broke HTML attribute parsing.
The browser would misinterpret xmlns="http://www.w3.org/2000/svg" as separate HTML
attributes, causing broken image rendering.
Changes:
- Add FALLBACK_AVATAR_DATA_URI constant with base64-encoded SVG
- Replace all instances of broken inline transparentPixel variable (3 locations)
- Update comparison check to use the new constant
The base64 encoding ensures the data URI is safely embedded in HTML src attributes
without any quote-escaping issues.
- Add getSafeThumbnailUrl() helper function with comprehensive error handling
- Replace all getThumbnailUrl() calls with safe wrapper that validates results
- Use SVG data URI placeholder instead of 'img/user-default.png' to avoid 400 errors
- Update img onerror handlers to fade opacity instead of trying invalid fallback paths
- Add detailed console logging for debugging avatar loading issues
- Improve updatePersonaAvatar() to only update src when valid URL is available
This fixes persistent 400 errors on some Ubuntu systems where directory names
with spaces (e.g., "User Avatars") caused thumbnail URL construction to fail.
Affected functions:
- getSafeThumbnailUrl() (new)
- updatePersonaAvatar()
- renderUserStats()
- renderCharacterThoughts()
- Fixed persona avatar loading for custom user profile folders with fallback
- Added dynamic persona avatar updates when user switches personas
- Fixed together mode bug where committedTrackerData wasn't persisting after first generation
- Together mode now mirrors separate mode logic for swipes vs new messages
- Converted all CSS font-sizes from rem to vw for proper responsive scaling
- Fixed weather widget scaling issues at high zoom levels
- Added image generation detection to skip tracker injection for quietImage requests
- Removed CHARACTER_MESSAGE_RENDERED listener to fix race condition in together mode
Implemented Visual Viewport API integration to detect and handle mobile
keyboard appearance, preventing contenteditable fields from squashing
the panel layout when the keyboard appears.
**JavaScript Changes (index.js:1886-1948, 522-523):**
- Created setupMobileKeyboardHandling() function:
* Uses Visual Viewport API to monitor viewport height changes
* Detects keyboard appearance (viewport < 75% of window height)
* Adds .rpg-keyboard-visible class when keyboard shows
* Removes class when keyboard dismisses
* Gracefully falls back if API not supported
- Created setupContentEditableScrolling() function:
* Uses event delegation for all contenteditable fields
* Automatically scrolls focused field into view with 300ms delay
* Centers field in viewport using scrollIntoView with 'center' block
* Smooth scrolling animation for better UX
- Added both function calls to initUI() for automatic setup
**CSS Changes (style.css:3232-3252):**
- Added .rpg-keyboard-visible state styling:
* 20px bottom padding to prevent content being pushed too far up
* Compact section padding (8px 12px) for stats/info/thoughts
* Reduced stat bar gap (4px) to maintain layout integrity
- Scoped to mobile viewport only (@media max-width: 1000px)
**Benefits:**
- No layout squashing when keyboard appears on mobile
- Stat bars and charts remain intact and visible
- Focused fields automatically scroll into view
- Smooth animations for professional UX
- Works with all contenteditable fields:
* Stats (health, energy, hygiene, sustenance, arousal)
* Inventory and mood/conditions
* Info box widgets (date, weather, time, location, temperature)
* Character traits and relationship badges
* Character thoughts
- Backward compatible (graceful fallback)
- Desktop users completely unaffected
**How It Works:**
1. Visual Viewport API monitors viewport height changes
2. When height drops below 75% threshold, keyboard detected
3. Panel gets .rpg-keyboard-visible class for compact styling
4. Tapped contenteditable field smoothly scrolls to center
5. When keyboard dismisses, layout returns to normal
**Testing Completed:**
- Inventory field editing works without squashing
- Stat values editable with keyboard visible
- Info box widget editing maintains layout
- Character traits and thoughts remain accessible
- No layout breaks or chart distortion
- Smooth scrolling and transitions verified
Completely redesigned the classic stats (STR, DEX, CON, INT, WIS, CHA)
section for mobile with 1/3 size reduction and vertical stack layout.
**CSS Changes (style.css:3510-3587):**
- Changed from vertical flex list to 2x3 CSS grid layout
- Reduced all dimensions by ~66% for ultra-compact mobile view:
* Labels: 9px (was 12px)
* Values: 14px (was 20px)
* Buttons: 24x24px (was 36x36px)
* Padding: 4px 6px (was 8px 10px)
* Gaps: 2-4px (was 6-8px)
- Vertical stack layout within each stat box:
* Row 1: Label (left) | Value (right)
* Row 2: Minus button (left) | Plus button (right)
- Fixed button visibility:
* Added explicit background, border, and color styles
* Added display: flex !important to ensure rendering
* Added hover and active states
- Fixed right-side cutoff:
* Added 5px padding-right to stats grid
* Adjusted margins for proper spacing
- Centered all elements using justify-self: center
- Removed conflicting @media (max-width: 768px) rule that enlarged buttons
**JavaScript Changes (index.js:518, 985-1011):**
- Created setupClassicStatsButtons() function with delegated event listeners
- Moved event handlers from renderUserStats() to setup function
- Used jQuery .on() delegation to persist across re-renders
- Prevents duplicate handlers and ensures buttons always work
- Called in initUI() during extension initialization
**Benefits:**
- Attributes take up 1/3 the vertical space on mobile
- No vertical overflow in mobile Stats tab
- All 6 attributes fit comfortably in 2x3 grid
- +/- buttons visible and properly aligned
- Buttons fully functional with delegation pattern
- Desktop layout completely unaffected (>1000px)
**Layout:**
```
┌────────────┐ ┌────────────┐
│ STR 13 │ │ DEX 16 │
│ - + │ │ - + │
└────────────┘ └────────────┘
┌────────────┐ ┌────────────┐
│ CON 14 │ │ INT 18 │
│ - + │ │ - + │
└────────────┘ └────────────┘
┌────────────┐ ┌────────────┐
│ WIS 13 │ │ CHA 15 │
│ - + │ │ - + │
└────────────┘ └────────────┘
```

- ES6 DiceModal class with proper state management (IDLE, ROLLING, SHOWING_RESULT)
- Semantic HTML with ARIA attributes for accessibility
- CSS state classes (.is-open, .is-closing, .is-animating)
- Touch-friendly 44px minimum tap targets
- Desktop enhancement with @media (min-width: 1001px)
Fixes:
- Fixed mobile viewport overflow with min-height: 0 on flex children
- Reduced max-height to 70vh for guaranteed mobile fit
- Removed all jQuery .show()/.hide() inline style injections
- Removed !important CSS hacks from mobile media query
- Fixed transparent modal background (80% opaque neutral gray)
- Darkened backdrop overlay (85% opaque black)
Technical:
- Backdrop uses ::before pseudo-element (no wrapper div needed)
- Flattened HTML structure with proper semantic elements
- Backwards compatible wrapper functions preserved
- Grid layout for inputs (stacked mobile, side-by-side desktop)
- Proper CSS specificity hierarchy (no !important needed)
- Removed .rpg-dice-popup-overlay div dependency
Accessibility:
- role="dialog" with aria-modal="true"
- aria-labelledby for dialog title
- aria-live regions for dynamic content
- aria-busy for loading states
- Proper focus management on open/close
Added matching slide-out animation when closing the mobile panel to
match the smooth slide-in animation on opening:
CSS changes (style.css):
- Add .rpg-mobile-closing class with rpgSlideOutToRight animation
- Create @keyframes rpgSlideOutToRight (0.3s ease-in-out)
- Panel slides smoothly off-screen to right before hiding
JavaScript changes (index.js):
- Add closeMobilePanelWithAnimation() helper function
- Use animationend event to wait for animation before hiding
- Replace all instant removeClass() calls with helper function
- Maintains smooth 0.3s animation timing matching slide-in
Implementation details:
- Helper function adds .rpg-mobile-closing class
- Waits for CSS animation to complete via animationend event
- Then removes closing class and overlay
- All close operations now use this helper for consistency
Result: Panel now smoothly slides in AND out with matching 0.3s
animations. No more jarring instant disappearance on close.
Improved thought icon behavior on mobile with smooth 60fps animations
matching the FAB button drag experience:
CSS changes:
- Add transition properties for top/left position changes
- Use 0.2s ease-out timing for smooth, natural movement
- Add will-change: top, left for browser rendering optimization
- Applied in mobile media query (@media max-width: 1000px)
JavaScript changes:
- Wrap position updates in requestAnimationFrame()
- Cancel pending RAF before scheduling new update (debouncing)
- Sync position updates with display refresh rate
- Same pattern as FAB button smooth drag implementation
Technical details:
- RAF throttling prevents layout thrashing
- CSS transitions handle the actual animation
- Combined approach gives 60fps smooth tracking
- Icon follows avatar smoothly during scroll on mobile
Result: Thought icon smoothly tracks avatar position during scroll
instead of jumping around, with buttery smooth 60fps animation.
Improved the mobile floating action button (FAB) drag experience with
smooth, performant animations:
- Use requestAnimationFrame to throttle position updates during drag
- Add will-change CSS property to optimize rendering performance
- Add dragging class to disable transitions during active drag
- Change cursor to grab/grabbing for better visual feedback
- Remove janky direct CSS updates in favor of RAF-based updates
Technical improvements:
- Position updates now synced to display refresh rate (~60fps)
- Prevents layout thrashing from excessive DOM manipulation
- Smooth transition animations when drag ends
Result: Dragging the FAB button now feels fluid and responsive on
mobile devices instead of laggy and jumpy.
Fixed two mobile UI issues:
1. Relationship badge sizing on mobile:
- Badge was stretching vertically due to .rpg-editable mobile styles
- Override padding, min-height, and line-height for badge on mobile
- Keep badge at compact 18px × 18px to prevent covering avatar
2. Thought panel initial state:
- Panel was showing by default instead of the icon
- Fixed initialization: hide panel, show icon
- Users now click the 💭 icon to open the dialogue as intended
Changes ensure proper mobile experience with appropriately sized UI
elements and correct initial visibility states.
Previously, the thought icon button was positioned to the left of the
character avatar on mobile, causing it to appear partially off-screen
due to lack of left padding around avatars.
Changes:
- Add mobile-specific positioning logic in index.js to detect viewport
width <= 1000px and calculate centered horizontal position
- Add CSS transform in mobile media query to shift icon 50px right
and 45px upward from calculated position
- Center thought panel horizontally on mobile when opened
- Add debug logging to verify mobile detection
Result: On mobile, the thought icon now appears above and to the right
of the avatar, fully visible and accessible.
- Add constrainFabToViewport() function with top-bar awareness
- Only constrains when mobileFabPosition exists (user has dragged button)
- Respects SillyTavern's top bar height via CSS variable
- Prevents button from being hidden behind UI elements
- Applies constraint after drag operations and window resize
- Remove verbose debug logging from drag/touch event handlers
This implements a state-driven approach where the constraint only activates
for user-positioned buttons, allowing CSS defaults to work naturally while
protecting custom positions from viewport changes.
- Fix inverted chevron logic: show left arrow when panel open, right arrow when closed
- Move FAB button from right to left side of screen (12px from left edge)
- Adjust vertical position down by 30px for better placement
- Update console logging to reflect correct icon states
Add full mouse and touch support for mobile toggle button with drag-to-reposition
functionality and persistent position saving.
Changes:
- Add mobile FAB button with draggable positioning (both mouse and touch)
- Implement time-based drag detection (200ms or 10px threshold)
- Add position persistence in extension settings
- Fix click handler to work on both mobile and desktop viewports
- Add comprehensive diagnostic logging for event debugging
- Update mobile panel to slide from right (matching desktop UX)
- Implement dual-button pattern (FAB + internal collapse toggle)
- Add viewport-constrained dragging with 10px padding
- Prevent click events from firing after drag completion
Mobile UX:
- FAB visible when panel closed, hidden when open
- Internal collapse toggle visible only when panel open
- Touch and mouse drag support with real-time positioning
- Click/tap toggles panel, drag repositions button
- Position saved across sessions
Technical:
- Add mousedown/mousemove/mouseup handlers for desktop drag
- Add touchstart/touchmove/touchend handlers for mobile drag
- Remove broken viewport check that prevented mobile clicks
- Add 'just-dragged' flag to prevent click after drag
- Update .gitignore to exclude CLAUDE.md and .env files
- Reorganized User Stats: moved portrait and inventory side-by-side, removed header
- Fixed Info Box widgets: made them square-shaped with proper scaling at all zoom levels
- Fixed stat bars: added overflow scrolling to prevent overlapping with mood box

- All elements now scale properly from 100% to 150%+ zoom
- Add bottom-sliding drawer system for mobile (≤1000px viewport)
- Implement tabbed navigation with Stats and Info & Characters tabs
- Combine Info Box and Present Characters into single tab with 50/50 split
- Add smooth transitions between desktop and mobile layouts
- Reposition collapse button as close button on mobile

Mobile Stats Tab:
- Use CSS Grid layout for efficient space utilization
- Portrait centered at top, stat bars below
- Inventory and mood on left, attributes list on right
- Convert attributes from 3x2 grid to vertical list
Mobile Info Box:
- Scale dashboard widgets to fill allocated space
- Proportional row heights (60% top row, 40% location)
- Widgets expand to fill available vertical space
Technical improvements:
- Bottom-based drawer positioning instead of transform
- CSS-only transitions, JavaScript only toggles classes
- Instant tab setup on desktop→mobile for smooth transition
- Temporary transition disabling for mobile→desktop snap
- Proper flex hierarchy for space filling
- Add pendingDiceRoll variable to store temporary roll result
- Clicking X or overlay now discards the roll without saving
- Only save to settings when user explicitly clicks 'Save Roll' button
- Prevents unwanted rolls from being saved to the sidebar display
- Convert font-size from px to rem for better accessibility
- Convert padding/margin/gap from px to em for responsive scaling
- Convert width/height/position values to rem
- Convert letter-spacing and transforms to responsive units
- Keep shadows, small borders (1-3px), and media queries as px
- Fix buttons (Manual Update & Settings) to use 100% width and 2.5rem height
- Fix TypeScript error: add missing id property to regexScript object
- Changed property name from quietPrompt to quiet_prompt (underscore notation)

- Fix inventory box stretching issue by adding max/min height constraints
- Inventory items now scroll internally with flex layout
- Remove bottom margin from Enable Immersive HTML toggle
- Add top margin to Manual Update button to maintain spacing
- Adds ensureHtmlCleaningRegex() function that automatically imports a regex script
- Regex removes HTML tags from outgoing prompts to prevent formatting issues
- Only imports if not already present (checks existing scripts by name)
- Based on the regex-clean_html_(from_outgoing_prompt).json specification
- Runs on extension initialization
- Non-blocking: won't fail extension load if regex import fails
- Added floating action button (FAB) that appears only on mobile (≤768px)
- Panel becomes a bottom sheet modal on mobile instead of fixed sidebar
- Smooth slide-up animation with backdrop overlay
- Panel hidden by default on mobile, opens when FAB clicked
- Touch-friendly button sizes (44px minimum per Apple HIG)
- 70vh height on tablets, 80vh on phones for better usability
- Rounded top corners for modern mobile UI
- Desktop behavior unchanged
- Changed from $('#sheld').after/before() to $('body').append()
- Panel is now a direct child of body element
- Works better with SillyTavern's main flexbox layout
- CSS handles all positioning (no more DOM position logic)
- Changed to 'third-party/rpg-companion-sillytavern'
- User-installed extensions need the third-party prefix
- Template loader looks for scripts/extensions/third-party/[name]
- Changed import paths from ../../ to ../../../
- User-installed extensions are in data/default-user/extensions/
- Paths need one more level up to reach script.js and other core files
