I started out with the "Ultimate UI" mod but some things did not work for me. I have added/removed various addons to get what I want and although it is not perfect, it will do. :D

WOW mod's at http://www.curse-gaming.com/mod.php

i am liking the one u are using in the SS above. Ive tried out ctmod, gypsy, insomniax, and now im back to ctmod. But i am liking yours i might try that out,

"Ultimate UI" uses FlexBar, PopBar, AvgXP, Gymnast, Quest Minion and some other mods which I have removed.

I have kept the WOW action bar because my characters shapeshift and stealth and the WOW action bar is the easiest and most reliable but I have used "HideArt" mod to remove graphics and experience bar.
The experience bar and "AvgXP" have been replaced with the "Lax" mod which shows the character stats.

I have added a 12 action block on each side of the action bar using "HoloBar" "HoloGemini" "HoloEssentials" mods.

I have a mod to automatically change weapons when I change stances "StanceSets" and one to easily rebuff weapons "WeaponRebuff".

The "AllInOneInventory" mod has a fault (can stretch the tooltip and ailments) but I can put up with that because it is very useful.

There are 2 essential mods "AlphaMap" which provides a transparent map and "MoveAnything" which enables you to move your layout around.
