Youtube Controller Hidden — SuperJohn

Youtube Controller hidden & Caption move freely
A free YouTube plugin for hiding/showing player buttons, keeping the playback progress bar visible, and more. It's completely free and safe.

1. The playback progress bar can be kept visible continuously by pressing Alt + J
2. You can hide/show the playback controller UI and the progress bar using Alt + K, L, H
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 "about:addons" -> ⚙️ Settings Gear -> Manage Extension Shortcuts

Feel free to use this free plugin, and have a great time playing!
