Hi Dave, after thinking about it a bit, I think the best choice for this is to remove those "selected" and "unselected" type sub-categories from the Scene Browser by default.

You'll be able to re-enable them by a setting in the moi.ini file and also if that is set I will update the scene browser when selection changes so that you should be able to avoid the workaround.

That way there will be some protection from any potential bad side effect from having the Scene Browser updated with every selection change.

The setting in the moi.ini file will be under:

[Scene Browser]
EnableSelectionSubTypes=n
