Changelog

• Plugin Startup Performance Optimization — Cached require('fs')/require('path') at module level to eliminate repeated require calls; cached styles.css content to reduce 5 disk reads to 1; batched all saveData() calls in onload() from 10+ async writes to at most 1; parallelized independent async operations (loadStyleCategories, loadGlobalRules, _preloadPinyinData) with Promise.all; eliminated duplicate style-categories.json reads in syncStylesToCategories; deferred cacheHoverStyles() to lazy-load on first use instead of blocking startup; fixed _preloadPinyinData() being called twice

• Remark Popup File Name Sync Fix — Fixed file name in remark popup not updating after renaming a note; handleFileRenameOrMove now updates links[].filePath in all rules (current file, global, and other files) and persists changes to disk

• Dark Mode Title Visibility Fix — Removed hardcoded #555 color from "Single Display" and "Always Display" section titles, now uses default theme text color for proper visibility in dark mode
• Single-display Tab Arrow Indicator — Added a downward-pointing triangle arrow below the active single-display tab, visually connecting the tab to the content panel below

• Release Asset Fix — Fixed missing main.js and manifest.json in v1.7.2 GitHub release assets

• Group Button Default Style — Changed group button default style from blue background with white text to white background with black text; custom styles now properly override the default
• Single-display Tab Element Fix — Changed single-display tab from <button> to <h4> element, fixing custom styles (gradient backgrounds, custom colors) not applying correctly
• Single-display Active State Persistence — Single-display group active state is now saved and restored when reopening the main panel

• Remark Badge Click Popup Fix — Fixed remark popup not appearing immediately when clicking the "n" badge to add a remark while hover delay is non-zero; popup now shows instantly and is protected from accidental mouseout cancellation
• Default Settings for New Install — New installs now default to: showRemarkBadge=true, remarkBadgeThreshold=2, popupLineHeight=1.5, popupBorderWidth=2, popupBorderColor=#ffffff

• Mobile Context Menu Fix — Fixed long-press style button options freezing, clicks not responding, and options remaining visible after closing the main panel on mobile
• Mobile Submenu Removal — Removed "Add as Heading Style" and "Move to Group" submenus on mobile (they rely on mouse hover events which don't work on touch devices)
• Remark Popup Hover Delay — Added setting to control how long the mouse must hover over matched text before the remark popup appears; moving the mouse away before the delay cancels the popup, preventing accidental triggers
• Add Group Instant Refresh — Fixed new groups not appearing in the main panel after adding; panel now refreshes immediately

• Single-display Group Pin Button Fix — Changed single-display tab 📌 button from inline to absolute positioning (matching always-visible groups), removed overflow:hidden that was clipping the button
• Main Panel Dark Background Fix — Injected !important CSS rule (.rch-transparent-bg) to forcefully override Obsidian's default modal-bg background, combined with MutationObserver for triple-layer protection
• Main Panel Lock Improvement — Lock button now directly sets pointer-events on modal-bg and modal-container to allow editor interaction when locked; fixed previously ineffective CSS class approach
• Lock Focus Stealing Fix — When locked, focusin events not triggered by user clicks on the panel are intercepted and focus is returned to the editor, preventing the panel from stealing focus
• Resize Handle Follows Panel — Right-bottom resize handle now updates position in real-time when dragging the main panel

• Popup z-index Improvement — Sub-modals (add group, rename, CSS editor, etc.) now appear above the main panel by raising their own z-index instead of lowering the main panel's, preventing Obsidian's sidebar divider from overlapping the panel

• Sticky Title Bar — Main panel title bar now stays fixed at the top when scrolling content
• Scrollbar Position Fix — Resizing the main panel no longer causes the scrollbar to jump to the left of the close button
• Removed Display Settings — Removed "Main Panel Opacity" and "Main Panel Width" settings from Display section; Ctrl+scroll and Alt+scroll shortcuts still work
• Instant Group Toggle — Toggling "Hide All Groups by Default" now immediately refreshes the panel instead of waiting for next open
• Popup z-index Fix — CSS editor and remark editor popups now correctly appear above the main panel
• Cancel Button Optimization — Clicking "Cancel" in CSS editor no longer triggers unnecessary UI refresh
• Toggle Collapse Performance — Expand/collapse operations no longer wait for file save, eliminating 1.7s delay after CSS editor closes
• Main Panel Open Speed — Deferred rendering of rules/settings sections, removed forced reflows, and batched font fixes for faster panel opening

• Rule Conversion Merge — When converting a rule between global and local, if a rule with the same regex already exists in the target, the cssClass is overwritten and remark/links are merged instead of blocking the conversion
• Popup Rule Source Badge — Added l/g (local/global) badge at the top-right corner of remark popup, always visible and clickable to convert rule source
• Remark Popup i18n — Translated hardcoded Chinese strings in remark popup (double-click to edit, no search text, no title, copy/open/delete remark) for English mode support
• Updated Remark Demo GIF — Replaced addremark.gif with new demo animation

• Pseudo-element Style Support — Add Style dialog now correctly previews and saves CSS rules with pseudo-elements (::before, ::after); pseudo-element rules are associated with their parent class
• @keyframes Animation Support — Add Style dialog now correctly previews and saves CSS rules with @keyframes animations; animation rules are placed below the main style rules; @keyframes blocks are stripped before class parsing to prevent false matches from decimal values inside keyframe definitions
• Remove Highlight Regex Matching Fix — Fixed bug where rules containing regex escape characters (e.g. \\.) could not be matched when removing highlights by selecting text; replaced direct string comparison with regex matching via textMatchesRegex() helper function
• Remove Preview Checkboxes — Removed checkboxes from style preview in Add Style dialog; clicking "Add Style" now adds all parsed styles by default
• README Add Style Demo — Added "Add Style" and "AI Create Style" demo GIFs to README in both English and Chinese sections

• Main Panel Group Button Style Customization — Added right-click context menu option to edit group button style class; supports custom CSS class preview and application
• Dark Mode Title Text Visibility Fix — Removed custom text colors from panel titles, style list/group labels, and settings text; now uses default theme colors for proper dark mode support
• Pin Submenu Button Repositioned — Moved "Pin Submenu" button to top-left corner of submenus to avoid blocking style buttons
• Submenu Direction Adaptation — Floating group submenus now open to the left when the group is on the right side of the screen, preventing overlap with group buttons on mobile
• Mobile Horizontal Scroll Fix — Mobile now limits modal width to screen width even when desktop saved a larger modalWidth value; prevents horizontal overflow caused by cross-device settings sync

• Fixed Callout Highlight Not Showing in Edit Mode — Added applyHighlightsToLivePreviewCallouts method to apply DOM-based highlighting to callout widgets in live preview mode; ViewPlugin's update now schedules callout highlight via debounced requestAnimationFrame; scroll and layout-change events also trigger callout highlighting in source mode
• Fixed Overlapping Decoration Ranges — Improved range sorting with secondary to key; added validation filter for invalid ranges; switched to Decoration.set(validRanges, true) to enable CodeMirror's internal sorting for safer handling of overlapping decorations from multiple rules
• Added Remark Demo GIF — Added addremark.gif to assets folder and referenced it in both English and Chinese Notes/备注功能 sections of README.md

• Custom Default Preview Text - Added "Default Preview Text" setting in Display section with separate Chinese/English input fields; when no text is selected, style buttons show custom text instead of default "示例"/"Preview"
• Fixed Clickable Title Text for Rules Sections - Clicking "Current File Rules" and "Global Rules" title text now correctly triggers expand/collapse; added pointer-events:none to h3 and description elements to ensure click events bubble properly
• Highlight List Search No Data Fix - When column filters match no results, table header with search inputs is now preserved instead of being cleared; "No data" message appears in tbody while search remains functional
• Visible Column Resizer - Column resize handles in highlight list are now always visible with a subtle border color; hover highlights in accent color
• Fixed Column Resize Affecting Other Columns - Dragging a column resizer now only adjusts the current column and its right neighbor (one grows, one shrinks); other columns remain unaffected
• Smooth Column Resizing - Cached table width on mousedown instead of reading DOM on every mousemove; eliminated layout thrashing for smooth drag experience
• Highlight List Performance Optimization - Used DocumentFragment for batch DOM construction; replaced per-row event listeners with event delegation on tbody; eliminated duplicate filter computation in stats display

• Remark Badge Indicator - Added "Show remark indicator at top-right of highlighted text" setting under Remark Popup section; hovering highlighted text shows a small "n" badge, clicking it opens the Add Remark modal; includes character threshold option

• Fixed Remark Popup in Edit Mode Callouts - Remark popup now works correctly in CodeMirror edit mode for text inside callouts; changed from classList.contains to closest() for upward DOM traversal
• Remark Popup Setting Name Fix - Renamed "确认后不自动关闭" to "鼠标离开不自动关闭"; remark popup now auto-closes after clicking confirm
• Global Highlight Rules Scrollbar - Added scrollbar to global highlight rules section when content exceeds viewport height
