Greasy Fork

v5.4.1

• Cleanup
  • Removed stale “embedded or floating” comment (floating mode was removed in v5.3).
  • Removed extra blank‑line remnant.

v5.4

• Cleanup
  • Reordered changelog from newest to oldest.
  • Consolidated duplicate v4.6 entries.
  • Fixed misplaced v5.2-diag.x entries.

v5.3.2

• Cleanup (Tier B)
  • Simplified diagnostic‑state tracking (kept DIAG_MODE toggle for future debugging).
  • Removed unused tooltip CSS (left/right arrows + tooltip‑main/hint selectors).
• Robustness
  • Made toolbar reinjection tolerant of transient form rerenders (reduces flicker; keeps re‑injection reliability).
• Fix
  • Removed stale reference to a non‑existent toolbar‑mode variable in post‑init verification.

v5.3

• Cleanup
  • Removed hybrid/floating/drag toolbar modes (back to embedded toolbar only).
  • Removed dynamic tooltip positioning + drag‑UI logic (keeps simple tooltips/hold‑to‑toggle).
  • Diagnostics disabled by default (can be re‑enabled for troubleshooting).
• Kept
  • Background‑tab safe init (prevents React hydration mismatch / error #418).

v5.2‑diag.2

• Fix
  • Do not mutate React DOM while the tab is hidden (prevents hydration mismatch / React error #418).
• Added
  • Deferred initialization (pendingStart) that runs only after the tab becomes visible.
• Diagnostics
  • Log when init is deferred due to background‑tab state.

v5.2‑diag.1

• Fix
  • Added missing diagnostic helpers (logStage, diagDOMState, initStages) to prevent ReferenceError on load.
• Diagnostics
  • Expanded debug output to help reproduce background‑tab initialization issues.

v5.2

• MAJOR
  • Hybrid toolbar mode – embedded when safe, floating on conflict.
• Embedded mode
  • Integrates into input area, non‑draggable (like pre‑5.0).
• Floating mode
  • Activated automatically if React removes the embedded button.
• Smart tooltips
  • Dynamically positioned to never be cut off by the viewport.
  • Hide during drag operations.
  • Explain right‑drag functionality.
• General
  • Toolbar appears only when a chat input area is present.

v5.1

• Fixed
  • Toolbar always visible on chat pages (dimmed when no code blocks).
  • Default position moved slightly more visible (bottom‑right, offset from edge).

v5.0

• Added
  • @match *://*canaryarena.ai/*.
  • Toolbar as a floating button (never injected into React DOM).
  • Right‑drag to move the toolbar button anywhere.
  • Position persisted per session (survives page navigation).
  • Tooltip on hover explaining controls.
• Fixed
  • No longer conflicts with other userscripts’ UI elements.
  • Works correctly when opened in background tabs.
• Removed
  • MutationObserver‑based toolbar re‑creation (no longer needed).
  • Form/textarea dependency for toolbar placement.

Added:

• @match ://canaryarena.ai/

v4.9

• Renamed from LMArena to Arena.ai

• Removed: width preservation on collapse (caused horizontal scrolling on narrow viewports)
• Collapsed blocks now use natural width instead of forced minWidth

// v4.3 // - Changed: single-block expand no longer uses scroll anchoring // - Expanding a block now keeps the header in place; code appears below (no viewport shift) // - Lets user read expanded code from the beginning instead of being scrolled to the bottom

// v4.4
// - Fixed: single-block expand now actively scrolls header to top of viewport
// - Ensures user always sees expanded code from the beginning (overrides browser scroll anchoring)

// v4.5
// - Refined: single-block expand only scrolls if header is in bottom 1/3 of viewport or off-screen
// - If header is already visible in upper 2/3, no scroll adjustment occurs
//
// v4.6
// - Fixed: single-block collapse no longer "snaps" the header down to the old footer position in some scroll states
// - Changed: when collapsing a block while its header is visible, the header is used as the scroll anchor (keeps it stable)
// - Fixed: auto-collapse on newly added blocks no longer triggers single-block scroll behavior
//
// v4.6
// - Fixed: single-block expand now first stabilizes the header position (cancels browser/scroll-area anchoring)
// - Refined: only scrolls header to top if it ends up off-screen or in the bottom ~15% of the viewport
//
// v4.7
// - Cleanup: removed unused `data` parameter from internal log function
// - Cleanup: removed unused boolean return values from createToolbarButton()
// - Cleanup: consolidated duplicate CSS rules and keyframe definitions

v4.1
- Cleanup: removed overridden CSS declaration (border-radius: 0 0 0 0)
- Cleanup: removed unused 'warn' log style
- Cleanup: removed redundant typeof guard for activeFixedState
- Cleanup: consolidated duplicate mouseleave handlers on collapse button

v4.2
- Changed: replaced localStorage with GM_setValue/GM_getValue for settings persistence
- Settings now stored via userscript manager (more reliable, syncs across browsers if supported)

v4.0
- Fixed: fixed footer now repositions when textarea grows during user input
- Added ResizeObserver on input area to detect height changes
- Footer no longer conflicts with/covers the textarea when it expands

v3.8
- Fixed: conflict with other userscripts (Multi-Provider Chat Export, etc.)
- Added 1000ms initialization delay to avoid React Hydration Error #418

v3.9
- Replaced hardcoded delay with dynamic Stabilization Observer
- Detects React hydration completion by watching for the chat input bar
- Uses requestIdleCallback for optimal performance/compatibility

Script name changed from "LMArena | Code Block Collapse" to "LMArena | Collapsible Code Blocks"
