Hi Filon!

I do (nearly) exactly what you describe for my group healin, although with HKN not IS, but as far as I know IS should work perfect for this...

..for getting the toon in the same order on all chars I use the following:

- pitbull as unitframes and us the 'sort alphabetical' option.
- grid also with alphabetical sorting turned on (this you have to specify in a lua-file, not in WoW directly)
(and kgpanels for showing buttonart as a graphical impression)
