Great!
For the second point: I was referring to doing nothing else but centering the sprite to the view. "Fit to frame" would zoom it in (thus messing with the zoom level) and 100% also centers the sprite to the view.
What I'd be asking is: Could there be button (preferably hotkeyable) somewhere easy to access that only sets the sprite to the center of the frame, leaving the zoom level intact? That way, reorienting oneself is just a button/hotkey away.
Again, thanks for the quick reply/fix!
