after trying out Pitbull I came to the conclusion that your unitframes are still the best solution for me :)
But it seems that there are a few bugs since the last 2-3 Releases of ag_UF:
1. Option "Show Combat-Text" doesn't work any more, not matter if you are in group, raid or alone
2. "Show number of Buff-Rows" seems to be borked too: You can only adjust your settings ONE TIME. After leaving this menue-instance it is nearly impossible to change the Row-Number, since the menu fades out so fast. This is only the case with the Buff-Rows menue-instance. A WOW-Restart solves the problem temporarily.
3. After joining a raid I had the Raid-Frames showing up (I disabled it because I have GRID). The only possible solution was to mark delete the mark from "Hide Frame" and set the mark again. I experienced this problem one time after joining a raid so I continue to investigate this behaviour.
4. Sometimes after joining a group, I only see myself and not the group-members - leaving the group and re-joining fixes the problem
There's definitely some weird bug both with ag_uf and sRaidFrames when you join a party or raid while in combat that causes the frames to not be populated correctly and remain bugged until you reloadui.
