I asked an LLM to analyze the current code quality.

There where 7 specific recommendations. Part two got sub-parts. Part 2.1:

Rendering Performance
Current state: Rendering functions (renderUserStats, renderInfoBox, renderThoughts, etc.) appear to re-render entire sections on every update.

Optimization opportunities:

  • Virtual DOM / diffing: Currently the extension re-renders full sections.
    • Implementing a lightweight diffing approach (or leveraging jQuery's DOM manipulation more surgically) could reduce reflow/repaint costs.
  • Debounced rendering:
    • Multiple render functions are called sequentially in rerenderRpgState(). These could be batched into a single animation frame using requestAnimationFrame.
  • CSS content-visibility:
    • For large inventory/equipment sections, content-visibility: auto would defer rendering of off-screen content

I'll work on this. Give me a moment to inspect the codebase and prepare a fix.

Rendering performance optimizations implemented! Here's what was done:

1. requestAnimationFrame batching

  • rerenderRpgState() now batches all render calls into a single animation frame via scheduleRender()
  • Multiple sequential renders are coalesced, reducing reflow/repaint costs

2. Lightweight change detection

  • New renderUtils.js module with updateIfChanged() utility
  • All render functions compare generated HTML against cached version before updating DOM
  • Event handlers only re-bound when DOM was actually updated
  • Skips unnecessary DOM teardown/rebuild when content hasn't changed

3. CSS content-visibility

  • Added content-visibility: auto with contain-intrinsic-size to inventory/equipment containers
  • Defers rendering of off-screen content until it enters the viewport

Rendering performance optimizations implemented! Here's what was done: **1. requestAnimationFrame batching** - `rerenderRpgState()` now batches all render calls into a single animation frame via `scheduleRender()` - Multiple sequential renders are coalesced, reducing reflow/repaint costs **2.
