To fix this it would require to change the serialization of TreeView and NbMainExplorer. It would also require adding methods to TreeView which is an API change. Marking target milestone as 3.4. Whether this is defect or enhancement is not clear. Maybe UI defect?
This is an enhancement since it introduces new functionality. Marking as such.
