Hey dudette, here's where you can get the best UI mods. Most importante is Profit UI. That one really saves space and makes detailed info more easy to read without crowdin' yo' shit. Do the Updater, then you don't have to fuck with a dozen little files every time there's a patch.
eq2maps is also super handy, as it loads a ton of info on every single zone, so you can find stuff more easily.
There are a few other UIs there, so before you choose one, you may decide to check them all out and look at the screeniez. Try to find ones on 1024x768, so you can get a better idea of your situation.
Hope this helps...screen real estate is costly.

Oh yeah, here's the URL--duh:
