I’ve a small set of global VSTs, Piano, E-Piano and per song VSTs like M-Tron, Minimonsta, Omnisphere, IK-Hammond, TAL Juno and in very rare situations more VSTs per song.
Because I use mostly same sounds and I like to use shared instruments, for me it would be nice to have a small list of VSTs which are in the song and global.
At now I see all default VSTs plus my VSTs used in parts, a very long list 
And … if it’s possible, not only show the shared symbol, the song/part titles also … and … the name of the used preset
