Essentially, a Burst creates a sub-tree in Project Data.
The user should be able to review this sub-tree while still in the Burst section. As the right column w/ the Portlets represents the currently active Burst, we need a way to exchange the Portlet "view" for a "file" view here.
Maybe we can do a 3D card flip on this column.
UPDATE: 3D card flip is ruled out after early tests. Will have to think about s.th. different.
