I always wanted a UI that felt like “me” and I’ve played around with a lot of different ones. Some more successful than others. Looking back at some old screenshots I sometimes wonder what I was thinking at the time. For a while I even had a different UI for my warlock and my warrior – in the end though that wasn’t very good and difficult to maintain – so I’ve since settled on one UI that I use for all of my characters.
The main UI itself is called SpartanUI and is very clean and user-friendly with minimal setup. Personally I usually disable the Party Frames mod since I use Grid which is much smaller and has all the info I need. SpartanUI incorporates Bartender 4 and oUF (party frames).
My one pet peeve with SpartanUI is that the target debuffs aren’t all displayed, it seems to be limited to a certain amount. Then again, I’m generally only interested in my own for which I use the debuff option in Quartz.
I know there are a lot of other options out there, such as DoTimer or ForteXorcist, but I never felt entirely comfortable with either of them – both of them always giving me a lot more information than I ever felt I wanted or needed. And so recently I’ve stuck to just the simple Quartz one.
Other little neat things just for sake of ease/fun:
Atlas & Atlasloot
ViperNotify (because on my hunter I keep forgetting to turn it off )
Obituary (prints out the killing blow of your fellow players’ deaths)
Lightheaded (wowhead in-game <3)
