The new UI is well, the new UI. Like it or lump it, it's what we've got.
While I have other opinions about some of the changes (I see my avatar on-screen all the time and don't need to see my photo in the corner)... there's one thing driving me up a wall...
The currant indicator.
It's all lost and alone down at the bottom of the screen. Worse, it's transparency is hard to read on certain backgrounds. I use the Toxic Moon for my home street - the grey on grey is impossible. I often navigate streets with my mouse so it tends to get in the way.
I'm not trying to be hard on the UI, it's got a couple of advantages over the old one. It's a bit cleaner, and the links are easier to find... but it still feels somehow... disconnected.
