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
- 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
- Implement FAB toggle button for opening mobile drawer
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
