A dashboard UI that suits my style is something I too have yet to see in EQ 2. I used Tablets in EQ 1 which was a great modular UI that fit together nicely no matter how the windows were arranged.
Here's a shot of it. The Tablets creator has an EQ 2 version but it's just not my thing and seems too far removed from what I liked about the original. I try lots of different UI's out all the time so I'm hoping one of them eventually jives with what I want and need as a raiding-healer-that-hates-funky-health-bar-designs-and-wishes-she-had-the-/viewport-command-back.
