There's something I can't get over in the way Project folders are displayed.
When in Project view - if I click on the 'Library' folder, I see all projects regardless of the sub-folder they're in, like this:
If I click on a sub-folder, I see....nothing.
It seems logical to me that if you clicked on any folder - it should display all the projects in that folder! This way you can quickly jump around and look at project groups by category - work projects, home projects, etc.
