Can you move a subfolder up to the top level?

+ Top A
+ Top B
+ Top C
++ Sub A
++ Sub B
++ Top D oops
+ Top E
++ Sub C
+ Top F

For example, I don't want Top D to be a subfolder in this list. I'd want to move Top D up a level in the hierarchy. How do you do that?

Hmm, it used to be draggable on top of the "Mtg Decks" to move it to top level but it seems it does not work indeed.

I will take a look.
