Hikaru and GothamChess Tell You to MOVE von Jack Li

This extension is for chess.com and lichess.org.

When you have spent too much time thinking on a singular move, Hikaru and GothamChess (or a generic sound effect if you're a boring person) will tell you to MOVE! You can adjust how long it takes before it reminds you to move, either a flat amount of time or a percentage of your remaining time.
