Not sure this would be that cool, but maybe it's the 'Spilled out' term - what does that actually mean?
What would be cool (and maybe this is what is meant by spilled out), would be the ability to create a View Group (scene) that can be easily recalled/edited in UC.
So, not just 'Drums' bus, but on 'Drums' bus, have a 'create View Group' option (ideally with a 'dynamic' option so if channels are added/removed from that bus the View Group changes with it...or not if locked). But also to have a general 'Create View Group' option for any combination of faders (e.g. 'my monitor mix faders that are important to me').
This is more for live than in studio situations, but UC is (or at least should be) for live, as S1 has everything required for studio.
When using UC on a tablet, working with 32 faders on a 9" screen is not fun.
If this is what is meant by 'Spilled out' - then yes - very cool!
