Youtube Controller hidden & Caption move

1. The playback progress bar can be kept visible continuously by pressing Ctrl/Cmd + Shift + U. 2. You can hide/show the playback controller UI and the progress bar using Ctrl/Cmd + Shift + i, O, P. 3. Subtitles can be freely moved and locked in position. 4. I don't like these default shortcuts. This configuration is designed to avoid key conflicts. You can also reconfigure the shortcuts in Extension -> Keyboard Shortcuts. Feel free to use this free plugin, and have a great time playing!
