Maybe we need a thread of the things we like in the new UI? Things can always be more better different; even if you like them! It's easy to forget to mention the things that went so smoothly. Without touching on any of the things which make the UI less accessible for you... What do you like?
I like the new tooltips. We were starting to get them in the old UI, but they just seem more solid now, very useful for a game with so many rabbit-holes to go down.
I like the clarity of the new map symbols. And having a mini-map! I don't need to choose between my inventory and the map anymore.
The new channels... Well, I haven't set them up yet, but I do like having customizable channels. It's awesome. I've been expecting it for years, since the old UI hinted at it.
The new details on abilities; abilities aren't just 'where did I get this?' any more.
The parchment color on containers; I no longer forget which one is my inventory and which isn't. And on NPCs! OMG I was always missing the drag and drop on NPCs because I couldn't see the black slot on dark brown.
Big, consistent buttons on the loot and NPC screens. More of this, please!
The 3D headshots... Okay, they make me laugh. But I love how they show which direction my target is from me. I can tell if the guy I'm aimed at is running away or not! That's just... I don't think I've ever had that in a game before.
Changing Icon and Text sizes. This is so... I needed this. Alot. The icons before were so teeny-tiny. And while the text was usually good... It didn't always work for me on my big screen. Now if it doesn't work, I can change it.
And as I've already said - out of the box, the layout worked on windowed mode on 768p and full-screen on 2048p. That's just pro-level work there.
Anyone else?
