How're you getting button highlights based on weather they're on the target or not? :o Dunno if it's default Bongos behavior or not.
it's a standard bongos feature. little bit bugged (really just a little bit ... sometimes heroismn pops up as "highlighted" but its not active, cause my trinket buff has the same name) but ... love it!^^
All those people posting their ZMC+UnitFrame combo's have corrupted me to give into trying them out =P Really fun to mess with so far though, just wish the pitbull portrait module could be positioned and sized like that (without changing the addon code) - but oh well pitbull already has given more than enough already.
