It would be helpful if the Label Class window in ArcGIS Pro had the little question marks that you can mouse over and view a quick explanation of a tool or function. In many of the drop-down sections in the "position" tab of the Label Class window, it is not obvious what the function will do (e.g. the "Overrun" option under Label Class --> position --> fitting strategy). I often find myself having to search the meaning of certain functions or just test how they work through trial and error, but it would be convenient if the "Help" pages were built into the Label Class window like they are in many other tools.
