IWBNI there were some visual indication on the Finale Window of the identity of the current staff set whenever a staff set is being displayed.
For example, the title of the window might read:
Finale 2000 - [myfile.mus] - Staff Set 2
This could be even more informative if it were possible to name a staff set (and create an arbitrary number of them). Then one might see the following window title:
Finale 2000 - [myfile.mus] - Horns
or
Finale 2000 - [myfile.mus] - Winds
