I wasn't sure at first what the blue < and > arrows on the Adjustable-Divider meant, but the expand and collapse is a nice feature! :)
Couple of things:
1) When fully expanded, the blue resize handlebars are still visible, and...
2) Also when fully minimized, it is also visible.
This could be miss-interpreted as being able to pull it back up / down.
