I've not been able to find a good mod for the following:
Concept: Raid group arrangement & class dispersion.
Additional: Drag&Drop template setup without having to re-arrange raid groups until satisfied with arrangement.
Ability to remember multiple templates.
Intelligent Templating - Switch class for class, raid function for raid function (healer, dps, tank, dispeller, etc.)
Use with 10,15, 25, 40 man groups.
Broadcast (raid warning or whatnot) on group change.
