Tortoise is quite correct in that Track Manager was as buggy as hell in most previous versions.
 
I would have to switch between Track & Console views multiple times, trying to get my changes to "stick", and it was nothing to do with the sync setting.
 
It would appear that this has improved in Splat. I'll give it a full workout later today to (hopefully) confirm.

I haven't been using this at all because it just did not work - especially in conjunction with a control surface ... hiding tracks just screwed everything up located on the right hand side of the 1st hidden channel (ACT control, adjusting AUX sends, etc) ...
 
I wonder what you'll tell us after your "workout" ... whether it 's worth giving it a try with SPlat (I did try with every major update of the X series and got disappointed so I haven't done it with Splat yet)
