It would be very useful (for capture screen as an example) to be able to have images displayed full screen, without anything added on it.
Things are better now, but not completely: when user zooms the image more than "fit to screen", a small navigation windows appears at the right bottom corner

Please make this navigation tool optional as the other informations/bars that can be displayed above the image.
I would suggest, in Settings > Fullscreen, something like this:
☑ Show additional: .. ☐ navigation window
..........................☐ playbar
..........................☑ info
..........................☐ scrolbars
..........................☑ toolbar
..........................☐ mouse cursor
If "show additional" could have a shortcut it would be very great, but even without, with this suggestion F12 and a single click would be sufficient to quickly get rid of all additional stuff displayed then turn them back
Thanks for listening
