I currently use Pitbull on my main PC, as it makes it incredibly easy to see all 5 Warlocks and all 5 Minions at once, plus it can display casting bars for each Warlock and target-units for each, so I can make sure they're earning their keep without having to check the second PC all the time

However, I'm getting close to mooching into AV and I'd still like to see my 5 Warlocks and their pets, even if we're not in the same group.
I don't want to display all 40 unit frames, as I'm not gonna be healing the other 35

Is there anything that can filter raid unit frames based on a set of names, for instance, or guild, something like that?

What does everyone else do when raiding?
