Issue 127: Restored the floating Subtitle History window on the right.

(2026-06-16) V3.6.7: 1. Issue 126: Fixed mismatched Netflix subtitle XML sources and errors when prefetching subtitles for the next episode. Intercepts Manifest JSON to build a downloadable_id -> movieId mapping, accurately associates XML subtitles with the correct movie or series ID, and prevents background prefetching from overwriting current subtitles while assigning them correctly. (2026-06-14) V3.6.6: 1. Issue 120: Extracted jQuery from background.js into libs/jquery-3.7.1.min.js, using the same external file in Chrome and Firefox packages. 2. Issue 121: When Netflix prefetches the next episode's subtitle XML, subtitles whose movieId or subtitle name cannot be confirmed are stored separately and do not overwrite official subtitles. 3. Issue 122: Added three favorite profiles each for primary and secondary subtitles. Switch between them using tabs on the respective subtitle pages, click to apply, and double-click a name to rename it. 4. Issue 123: Added a JSON textarea for exporting and importing all six profiles. Opening the Favorites tab displays current settings; importing overwrites the six profiles on the current computer. 5. Issue 124: The subtitle settings window now closes via the X in the upper right or the O hotkey and is hidden using low opacity and z-index, preventing blur / mouseleave from closing it while adjusting colors. 6. Issue 125: Fixed secondary subtitles incorrectly reading the primary subtitle's saved settings when changing videos. (2026-05-16) V3.6.5: 1. Issue 116: In 3.6.4, fixed the font download URL. 2.

Issue 112: Adjusted dual subtitle synchronization logic to reduce occasional primary and secondary subtitle desynchronization. 2. Issue 113: Added a floating Subtitle History window on the right for reviewing subtitle history during playback and learning. 3. Issue 114: Added a subtitle history switch under automatic features, enabled by default. When disabled, the right-hand subtitle area is hidden and subtitle content is no longer collected, avoiding additional CPU load. (2025-12-21) V3.6.1: 1. Issue 110: Fixed an issue in "律政伊人" season 1 episode 4 at 02:20 where an original two-line English subtitle became one line without a space when set as the secondary subtitle. 2. Issue 111: Fixed an issue with double-clicking the small window at the end to enter full screen. (2025-05-17) V3.5: 1. At Sawa Natsu's request to increase font size 3 further, changed the maximum to 8. 2. 007 PP reported that dual subtitles stopped working; line breaks were found mixed into subtitles recorded in localStorage. (2024-02-11) V3.3: 1. Issue 100: Added the font option Noto Sans TC https://fonts.google.com/noto/specimen/Noto+Sans+TC 2. Issue 101: Added the font option GenYo Gothic https://github.com/ButTaiwan/genyog-font 3. Issue 102: Added the font option GenSeki Gothic https://github.com/ButTaiwan/genseki-font 4. Issue 103: Added the font option Iansui https://github.com/ButTaiwan/iansui 5. Issue 104: Added the font option LXGW WenKai https://github.com/lxgw/LxgwWenKai 6.

Issue 96: Automatically skip recaps, for example 鬼滅之刃-刀匠村篇 episode 11. 2. Issue 97: Playback stops at the end and clicking the middle of the screen causes a freeze, for example 柯南 episode 159. Trigger: $("video").play(); Solution: When video duration equals currentTime, add css style.pointerEvents = "none"; to the video. 3. Issue 95: The player automatically exits at the end of the final episode, preventing users from returning to watch the credits, for example LiSA Live is Smile Always (From: Takashi_灯). Solution: Support double-clicking to return to full screen, but the track bar is invisible and unusable at that point. Operating it appears to cause a freeze, so it is hidden for now.

(2022-11-10) V2.7: 1. 90: Fixed all-uppercase English (CC) subtitles in Friends. (2022-11-10) V2.6: 1. Clearing subtitles from localStorage accidentally cleared subtitle settings.

Fixed flickering image-based subtitles. 3. Fixed an issue where, after the screen was idle for a while, users could not return to the previous page or click the report issue control in the upper right. 4.

Fixed subtitles being unnecessarily forced to uppercase: font-variant: small-caps 9. Primary and secondary subtitles can have independent styles. 10.
