I still feel like the game is losing direction even so. In my perspective, it falls into the view of EQ1 and old content losing both it's place and usefulness in the world. Cities used to be pretty sweet, now they're mostly just filled with a bunch of non-used NPCs and lower level quest characters.
But to stay on topic for the UI, pixel shader 3 isn't really along the line of the topic
It's pretty obvious that the interface could do with more possibility in the way of scripting. The most we get from Live Update to the next, is more Dynamic Data (sometimes) and more functions. A lot of the time.... we are getting what we thought we should have.... a long time ago

(fixes, strange processing of current scripting). And I'm just talking UI modding. Yes, we get new windows and new features from time to time.
Without more expansion to the scripting system, or an implementation of a new one (ie, LUA)... I think the current UI will always be behind it's time.
