My requests would be:
1. Off/online editor
2. DVI out for secondary display
3. Ability to use any combination of stage racks provided they dont exceed the capability of the mixer (i.e 2 x AR2412 or 4 x AR84 etc)
4. Not related to the current GLD per say, but expand the GLD line to include a rack mount version and perhaps a larger frame option (more faders)
Just a few that I would like to see on the system. 
Overall still a great product but missing the offline editor.
