Local YouTube Subtitle Loader от MagnusNSK

Adds an "SRT" button to the left of the original YouTube caption display button that allows you to load a local SRT subtitle file into the player, with similar appearance to the YouTube captions, but without overtaking or complicating the interface with unnecessary bloat.

The custom caption display can be moved with the mouse, and if you hold Shift before dragging, you can either increase or decrease the size by moving away from the caption's center or towards it, respectively.
