This is my revamped version of my UI specifically for a PvE Shadow Priest. - I plan on releasing it at some point under the name of 'Absolution UI' when I'm fully happy with it and it's been tested out in raid situations better. Non visible / hidden addons: Omen Threat Meter, Grid, Classtimers. Also a hidden bar for buffs and trade skills. Credits: Caze (Daggerspine EU) - Helped me no end with ideas and suggestions.

All the usual: Pitbull, bongos, geist, buffalo, omen, baudbag, recount, prat, fubar and a few assorted plugins, cowtip, eepanels2, simpleminimap, detachedminibuttons, parrot, quartz. Those are the main ones you can see.
