the vertical scroll bar to navigate through folders is extremely slow and unresponsive
The scroll bar is very slow to respond when clicked.
Also, I have quite a lot of folders. When I want to drag and drop one folder into another one which is not in screen at the same time, it requires extensive workarounds (e.g. first moving the folder up in the list so it gets closer to the folder I want to put it in). I'd much prefer to hold the folder over the scroll bar to scroll up or down so I can navigate to the position I want to drop the folder.
