Remove buttons on (left) Navigation Pane
It is very easy to add buttons to left Navigation pane. However, you cannot remove individual buttons.
The only option is to Reset the pane returning the three original buttons (thumbnails, bookmarks, attachments).
It seems there should be a way to remove individual buttons at will (not just reset).
