When dragging a file/folder inside a folder with too many subfolders, the user must hold the mouse over invisible bars at the very top/bottom in order to scroll through all those subfolders. I request that those two invisible bars become around 25% opaque when dragging.
Created attachment 174441 [details] These are the "invisible bars" I want 25% opaque.
Making it slightly visible will make people discover its existence, and make it a bit easier to use.
This seems reasonable to improve discoverability of the functionality
I've noticed this too, and it can be confusing at times. Please wait; I'm working on it. :)
