Is your feature request related to a problem? Please describe.
I have a number of characters on both factions on a single server. The end result is that I see characters I don't need to see while playing either faction.

Describe the solution you'd like
Could you please add a toggle to only show characters on your current faction?

Describe alternatives you've considered
This could also be resolved with profiles (ie, I could have a profile for Horde and a profile for Alliance)
