[FEATURE] Add option for always on overlay buttons controller mapping

[ushabuntu]

Just like in Anki - allow for an option to always show button overlays for easy navigation while practicing flashcards.

The situation ATM in remnote is good, but could be great.

The old button display was broken in a recent update. They used to be displayed under each response item. But I really like the Anki take on this! Will definitely look into this. ^^
