Something (YouTube) is forcing the standard aspect ratio in full screen

overriding your extensions change to the aspect ratio while in full screen.
please continue to support this niech but useful tool.

Same problem as this guy JP, Posted jan 30, 2021.

Not working.
It's stuck at "regular fullscreen size" not larger, but can be smaller...It zooms past 100% only when not at fullscreen.

Associate the video ID from the URL with the most recent setting?

I assume you have some way to save stuff to local storage. Can you save a table/dictionary/map that takes the video ID from the URL and returns the most recent custom aspect ratio? Anything not stored in the map would be assumed to be 100%, so it would only contain stuff set by hand, and you'd delete anything that was set back to to 100%, so it shouldn't eat up too much local storage space for the average user.

Hi, could you add 117/118% into the selection. It would be perfect for the Huawei Matebook 14. Now with it at 116%, there are still a slight black space on top & bottom. God bless!
