You have event select which is not same as track select - so no collection for selected tracks to filter on that.
There is IsHidden for track, so IsSelected maybe would be appropriate.
You have function to Select whatever you filter - but not unselect.
So an action to select or unselect tracks that you filtered out would be nice.
You have track operation for anything - but select/unselect of track.
We are seriously inhibited in doing many common operations unless this exist.
Let’s say you do a selection on tracks - and want to operate on those.
Thanks for any support.
