Please consider adding the ability to change the *Keyboard shortcut* for Cinema Mode.

Alt + Shift + End is mission impossible on my laptop... :'(

Love the addon,
Thank you! :-)

:like:

I'm very happy with this addon it gives me what I need on youtube (slow/fast speed, default *4K, HD).
I wish this kind of add-on can be added on android ;) (mmh maybe it can)

*Sometimes, it doesn't shows the 4K as default (why?).

This addon is very helpfull but it has some bugs - it spams many same elements (style and script - including usermade) into head of document. It can make browser slower as well as it takes more memory.
