• Fixed a karaoke bug where lines without an explicit \pos would sometimes flicker and stack.
• Added a workaround for a bug in the YouTube Android app (white text being displayed in the wrong color).
• Implemented a new workaround for YouTube's buggy subtitle padding (the extra whitespace at the beginning and end of each line) on PC. Background boxes are now always symmetrical, and right-to-left subtitles (such as Arabic) no longer get wide gaps in the midde.
• Fixed shadows not being hidden if their alpha is set to FF using \4a or \alpha.
• Added a new {\ytdir} tag for setting the text direction to RTL in LTR subtitles.
• Added a Fiddler script (CustomRules.js) for enabling subtitle preview on videos that have no subtitles yet.
