How about knowing basic stats on selection (= any objects selected) in the Project Browser?
When I'm selecting more elements from the project browser tree for deleting, suppressing, enabled, visibility, transparency, isolation, free move/rotate etc. I could really use basic stats on what I've selected. See the attached screenshot with manually edited stats at the bottom.
It's always better to know and have a mental check in your head before you proceed with the operation. Very little super simple thing that could save us headaches working with large assemblies.
Thanks,
cheers to Autodesk team.
