Popup window when minimized

[sleepingzzs]

Describe your suggested feature

I thought this feature would be convenient for some readers during zoom calls lol. So here's how it would work.

A small popup window appears when minimized while reading with buttons to change the page. This should be enabled through settings as others may find it annoying.
