Yes the old version I showed was more customizable. The elements should be able to be moved around and scalable to give different layouts as well as being able to remove icons so uses can create their own skin. Have custom menus to add whatever functions you like. This is all coming back to me again, as I remember posting animation of Adobe Audition skins/layouts and how easy it was.
There are also other DAW's that can have any skin from another DAW as well as behaviors.
IF it's going to be changed again allow it to be fully customizable (that means it can't be sold down the track with a different hard wired theme).
All this is so much easier to do with the JUCE BB Plugin and a lot better quality GUI, when it's programmed for Win it's also programmed for Mac at the same time not a half year later.
I think you need to take into account the future and the best way to make it sustainable.
A lot of us here are old users, you need to think about catering for new users down the track.
