It's great! I hate it when the UI keeps popping up when I pause or move the mouse. Now I can take a break and not spoil how much playtime is left. I wish the extension would remember my setting (so I would not need to enable it for every session), or at least have a keyboard shortcut to toggle it on and off.

works great

Works like a charm on Netflix. Could have some extra features like a hotkey, but does the job.
