Thanks for the available ear.
The problem of discovery is tricky. How best to find something when you don’t know where to look, or worse, when you incorrectly think you know where to look. I was in the latter camp, so there an exists a PEBKAC argument that I humbly accept as valid.
Is it the purpose of the tool to correct my incorrect assumptions? That doesn’t seem reasonable, but I think information organizational display tools should offer context to test the assumptions of the user. In this case, the UI failed me. The word ‘Scope’ in the Members’ field was not conceptually close enough to the word ‘Class’ for me to question whether I was looking in the right place.
I think the lowest effort that maximizes on returns here is to add a right click item on a member item that says something like “Display Class” if its current class is not selected in the Classes panel. Clicking that option would auto select that class, thereby repopulating the Members’ panel all while retaining the original member item’s selection.
