One thing I will never understand is why do me need to have animations at all? There is zero value on them. Worse I'm inclined to believe that they introduce a nasty amount of bugs and they also need to be maintained.
By having a clear animation which indicates where the window is being moved to, it’s obvious where the window went and thus how to recover it.
So what I don't get is the need to have half-assed animations in a half-assed app. You can add them once everything else is perfect.
