The current folder highlighting disappears after 1st opening with multiple folders open.
Folders are each highlighted during first opening of each of multiple folders, but when you click back on any of the previous still open folder tabs they are NOT highlighted in the Navigator file tree.
This makes additional navigation MUCH more difficult & frustrating.
I Just checked and it's the same in PM6 as well as the new PM6+.
It would be helpful if each open folder's tab's filename was highlighted in the Navigator tree whenever the folder tab is clicked on.
It would be especially helpful if all of the open folder's tab's filename were highlighted (ideally, if possible, in different colors for each) in the Navigator tree.
Even if they were all the same color you'd at least know which ones are open.
