Even when disabling mouse interaction the mouse interaction still persists. I use exclusively hotkey. Hotkey needs an option which prevents the mouse from being hidden automatically when in the bounds defined by the mouse interaction section, especially when the mouse interaction is turned off! It should use the default behaviour which is show the mouse until some time has passed.

I wish it had an option to also hide subtitles when I pause a video so that I don't have to separately turn the subtitles off then back on when I pause a video to do something like read text on the screen or examine a graph/chart.

It is working in youtube.com but how do I make it work in other websites where videos from youtube are being played for Example Khanacademy.org?

This worked perfectly for a while but now it's stopped working properly, basically I have to refresh the youtube video every time for it to work, which leads me to wonder, why is that the case? what is not happening that the refresh fixes?
