Ahhh yes, I forgot about that option... but the problem with that is that when you move the cursor out of the popup folder, it closes. I would like it to wait until the parent folder recieved a mouse click, or the title was double clicked to close it.

And the problem when pinning a popup is this... say you pinned the "Shortcuts" folder, and then opened another popup ("Shortcuts'" parent), if you hover the cursor over the "shortcuts" entry, the pinned popup will disappear, and "shortcuts" will appear next to its parent folder. I would prefer if nothing happened at all when you hovered over a pinned popup's entry in its parent folder, or maybe another copy of the same folder could be popped up.
