First off, this addon is absolutely fantastic. It's a lot of fun to use and really helps out. I'm working on modifying this addon for personal use to work outside of battlegrounds (to work in world pvp). I'm having some difficulty modifying the Configuration interface that would allow me to create a specific tabbed option to enable for world pvp (right now I'm working on piggybacking off of the 40 person sized BG).
Did you use a specific tool to help with the design of the Configuration UI?
