I absolutely love this extension. And the new thing with the subfolders is even better!
However, it sometimes occurs now, that the subfolder box appears somewhere on the screen and not anymore in relation to the original folder bar. But haven't figured out why and when this starts yet.
this is fixed since version 0.9.4 - you can contact me if you still have it with this version.
