I mainly use Cubase for recording bands and solo singers, one of the things to change is to be able to de activate loop region whilst recording…nothing worse when you don’t realise the loop is on and the track starts from beginning mid song!! some strange looks come from the vocal room! 
also on live drums, if played to a click track auto align would be awesome rather than edit hit points etc etc.
one last one… A lot of people are asking for the Vocal align, for backing vocals to sync with Lead vocals, that would be brilliant, That would be an actual time and work saving feature…
