Ok, so what I'm asking for doesn't appear to exist. I'll re-iterate to try and clear up any confusion.
I have 3 zones set up:
C:\Winamp Zones\Living Room\winamp.exe
C:\Winamp Zones\Kitchen\winamp.exe
C:\Winamp Zones\Basement\winamp.exe
They correctly display within zone>current when they are the currently active zone.
What I am asking for is to have my zone selection overlay buttons as:
zone>0
zone>1
zone>2
Instead of being hard coded. That way when I decide that the Basement doesn't need a zone anymore and I make it the Bedroom zone, all I do is change the zone config in XLobby, no re-skinning.
Admittedly this is a small thing, but that should make it easy!
