Project panel: folders should not open automatically when drag something onto it
I f you drag something onto a folder inside the Project panel the folder should not open automatically.
(Only if you stay on the folder with the dragged object/cursor)

... each closed folder turns into an open folder and stays open when I drag something onto it.
So I have to close it every time afterwards. So that's one needless click. -

Thanks for the feedback. I'm not seeing exactly that behavior, but there is one case where an open folder with something dragged out of it(so it is now empty) will remember that it's opened, even if nothing is in it. That means it shows opened when something gets added to it.
So, if you close the folder ever, it should stay closed permanently. Let me know if that's not the behavior you're seeing.
