I still feel the way fibery is structured in terms of app is not helpful when trying to arrange project views. Typically I and my project teams would like to display things along custom lines not entity lines(if you get my drift).
I would typically have the following setup with sub folders. I have even had program folders above the project node shown.
Having to stick with app specific folder views is quite limiting to be honest. One of the best things about TP is being able to setup such views of work and items and the process/workflows and entity types are left in the background.
