As for requests, as you seem to be going to re-wite it in VB6 to include with RR. Just to make it not a "Plug-in" as it's current state. But to make it like any other skin, and use RR buttons ect to control it. This way the size of list boxes, locations of buttons could all then be modified much more easily. This would then use the standard on, off, down images to show button presses ect, and not have to embed it as an application.
This sounds like where you are going already, but just wanted to see if that is actually how you plan on implementing it.
Road Runner is in MUCH need of a better internal search, and this is EXACTLY what it needs!
