It would be great to be able to switch between label classes at the top of this pane. Right now it requires some extra clicks, either the labeling tab on the ribbon and then the drop down there, or, if you happen to be in Map View (which I am not most of the time when I'm working on labels), you can use the list by labeling (would be great to have this in Layout: Access list-by-labeling TOC from layout view - Esri Community ).
The way labeling properties are controlled in Pro continues to baffle me, with controls strewn about in so many different places. This would help reduce the back and forth a little.
