Personally I don't think it is useful or necessary.  Name your setlists correctly and basta

I can see that when exploring software, especially after converting, missing features can seem an issue, but I keep being surprised at how many features MS does have.

So I agree that set list previews are a bit pointless, but I also wonder if this is because the software that the OP is coming from hasn't got the same features for collections so to organise things you end up using setlists?

So perhaps the OP needs to understand how collections, custom groups and other features allow you to manage songs.

In other words, what problem is the OP trying top solve with the Setlist preview? 

As I work across 4 different groups, having a clear plan for organising the music, which has both compatible and incompatible overlaps, is important. Understanding the MS way (or ways) would improve their song management.

I can see that if you are using setlists for library organisation then the original query makes sense, but if they use collections and other fields (I use custom group as Instrument) then the problem they are trying to solve might already have a MobileSheets solution that might work better. If I am exploring then filtering by Collection (essentially which band) and by instrument soon gets the collection down to a manageable size, and then the various search features of MS make it easy to navigate.
