Suggestion

Are you talking about 'Full Screen'?
Why not apply a 'Mouse Gesture'?

first of all, I don't use mouse gestures. Secondly, it is not very convenient to constantly make a mouse gesture, and when you need to go to another tab, exit this mode or scroll through a million tabs to the right or left with gestures. It is much more convenient if the top panel moves out when the cursor hovers over the top edge and disappears after that.
