Certain apps hide the mouse cursor, specifically games in my case, still allow the cursor to move freely, since the pop out is interactable & the cursor is hidden, you get taken out of the app unexpectedly and give the pop out priority as the active window.

This essentially would lock the pop up window until returning to the opera window with the unlock button being in the middle of the "playing in video popout".

Whether its a lock button on the pop out window itself or an option in settings I think this will be appreciated by more than just me, the amount of gamers that are on a single monitor setup which would be allowed indulge in 2nd screen viewing without the need to purchase another screen.

Combined with the usage limiters, this is the best quality pop out window I've used in terms of not dropping quality over time, it's just a shame that at times it can interrupt the flow.
