I think for VST that have a small screen footprint, suit the PC format, and are much easier to work with (especially if you have one screen) as VST have a lot of wasted space on them. I really like how the QuadCurve flies out to give the best both worlds. A VU meter would fit nicely, and a flyout to access details to set them up.
I have all but the gete and the soft tube modules. The ProChannel list fills two screen heights of a HD screen. A Lot to scroll through. If they develop anymore, the should really address this.
As the menu already has a sub menu (Style Dials), then it's already set up for sub menus. It would be great to veiw these by Manufacturer, or by type. The prochannels already have a type category assigned to them in the background. It's clearer on my theme, as I changed the colours of each type.
