I sometimes accidentally minimize the window for the app Quick Edit Pro, whilst working with it. I get the smaller variable size and position window that I can intentionally create for some apps by long press of the return button (Android 5, Samsung GN3).
But Quick Edit Pro does not appear in the list I get when long pressing the return button.
What kind of swiping movement do I sometimes perform unintentionally in the upper part of the screen, that minimizes the app to this useful window. (Going back to the full window is done by a simple button press.)
I have tried many times but can not repeat it intentionally.
I now find that it is called "freeform mode". I have not installed any special apps to enable it.
