This might not suit everyone, but - like Geoff above - I tend to have a collection per song and the collection containing, eg, lead Sheet, transposed arrangements etc with appropriate names. When I'm looking for a piece, I look in collections, then find the version.
Although, if it's simple, I just include everything in one song and, maybe, use
Links to navigate.
