Have you noticed that when you're in a sheet with no views activated, many categories in VV/VG are pointless? What if they overrode the VV/VG for views that are on that sheet? For example, you can hide 'Levels' in a sheet's VV/VG, but that does nothing, because you can't put levels directly on a sheet. But what if turning off Levels on the sheet turned off the Levels for all views on that sheet? Not sure how that would work if the the view was deleted from the sheet, but would be pretty cool. Maybe a 'View Template' you can assign to a sheet?
