I have used the default UI since launch and was hesitant to try something else. I installed ProfitUI last night and arranged it to my taste and WOW, I should have switched a long long time ago. The one click heal and cure buttons on the group and raid windows are exceptional.
I also love the one-click buttons for volume, video, zone reuse, etc. on the EQ2 start HUD (or whatever this window is properly titled). Just one question, I tried a number of ways to make this button group a little larger to no avail (doesn't appear possible from in-game). I assume it would require editing of the .xml file, but unsure. Does anyone know how I might enlarge this HUD? I didn't think my vision was that bad, but those buttons are a little too small for me.
In any case, thank you so much for such a great interface!
