I was thinking that it might be an interesting idea to have the option of chaning the ZUI view based on what the user is doing.
For example, if I set up a ZUI that had Plasmoids configured to help me do sound/music editing, when I happen to launch Audacity from the main menu, KDE automatically switches to the ZUI that applies (which I would have previously specified). Kind of like a "ZUI action-on" setting or some such thing that states, "go to this ZUI when this application/hot-key/etc is activated".
