Thanks for the suggestions, Benoist! I have been thinking of something like this myself... I like both, having nice big pages with visual information, like things are now, but also condensed views where I can see everything, so yes, I agree with both of us ;)
Have you seen the EDIT -> CV page, where you can see ALL of the CV input activity all at once? A page like that might work, where all 20 controls are visible all at once, with 4 selectable (columns or something, dunno yet) for editing with the knobs.
I have no idea how soon I can work on something like this (working on a lot of other things at the moment), but I am glad you mentioned it, as I have also been thinking about this.
Cheers! - Rob
