Easy way to drag'n'drop the current folder on a button

[RussWilliams]

Is there an easy way to drag'n'drop the current folder on a button in the button panel? I have tried to D&D the current tab, or a subfield from the current path field, but neither one works. It's a pain to have to go up to the parent folder and then look for the subfolder you were just in.

No there is no way to do that I think. But to good suggestion of a thing to add.

But not sure how to add it. Maybe allow the ".." folder to be drag n dropped on a button. How to think a bit about that. But I add it to my list.
