Some way to "Expand All" in the workspaces would be a huge time-saver.
I have quite a tree of workspaces, and many times throughout the day I have to open my way down through the tree to get to where I want to be.
It would be great to be able to hold down the Shift key while clicking the little "+" symbol, and have all of the branches of that tree open up. Holding Shift while clicking the All workspace could expand all branches.
Conversely, it could also collapse all...
