Similar to Session Templates, or I/O Setups I'd like to see the ability to select from multiple, user-defined ICON Templates (for D-Control and D-Command) that save the Operation & User Console Prefs, Custom Fader Groups, Plug-in Maps, etc. that could be backed up to a USB thumb drive.
This file would need to be saved within the Session folder hierarchy, but not be tied to it. In that, if I hand off my work to another mixer, they still have the ability to chose their own ICON setup even if they're working on the same system. But, 8 months down, when I restore the session on another system I don't have to insert the same USB key to have my setup available.
