This is a great addon, thank you for making it.
On the account of previous suggestions and reports i would like to add a minor addition.
First, the range check. Specially an adjustable one would be very handy for RBG leaders, for switching, crowd control, and adjustments.
Secondly, Maybe the option to have resource(mana/rage/runic) bars would be handy in some situations.
Thirdly, while the idea of having health bars may sound and look like a memory hog, if it is added combined with flag carrier(not so necessary as specs already show that somehow), the idea here is that even if it's a complete memory/cpu hog. You could simply add a special option for enabling it which has a mouse over red text that strictly suggests the nature of enabling it, with a UI reload action if needed.
Overall, this addon is great and i will definitely continue using it.
