D'oh - I just realized you can't see the castbars in this image.
Castbars actually show up in front of the background for each UF, but behind the HP/Mana bars and texts. I used Quartz - latency is embedded, dark red, no text; cast times show up below the UF, slightly overlapping it, lined up with the left side of the background frame. The castbar itself is a dark grey, so the white background becomes overlayed with a dark grey as the spell is cast. I'll get another up here tommorrow or so with a visible castbar. :)
And I think I'm going back to MonkeyQuest - TomQuest2 is nice, but MonkeyQuest lets me hide it easily while in instances/raids, while TQ2 is annoying to hide/show.
