Someone else posted something ArkiveUI in another thread. I checked it out real quick, it looks decent (not working either though).
One thing he did have was an
element template posted. I think that's a pretty good idea to lay out the elements. Mazzle switched between different views (Solo, Party, Raid) nicely, and IIRC there were multiple raid views. I think that a template for each view would be very handy during the development process, as well as to the end user. It should help figure out what options you have for various add-ons.
