Better late than never! After a few weeks since timestamps were only for show in preview, they are now also functional! You can click on them and the video will be at that timestamp. I've also added a new button that adds the current timestamp the video is playing to the comment box, so you don't have to manually type it out when commenting.

Updated icon! Also, buttons when hovering now uses YouTube's current color instead of always being gray, for those who use custom YouTube themes.

Added formatting for timestamps! Doesn't actually do anything, though, else it will completely refresh the page instead of actually at the timestamp.

Added UI! You can disable it in the options menu if you don't like it.

Removed Ctrl + Z and Ctrl + Y!
