There's no update since, is there?
....don't see any change in the Web UI ....
I'm using an android tablet with a 10 inch display and can scroll through the top window for artist, album or track - could the scroll bar on the right be slightly wider, also only lists about half of artists before finding the rest and then resetting scroll bar.
I find it easier to find an artist by looking at the album pictures instead of a list of names, it feels your going through you albums and thinking I haven't played that one for a while, oh, that one! , I'm playing that one next.
Also i like when you select an artist you get another list as you scroll down the screen of the albums and tracks, also works when you select the album or track. The buttons as highlighted in green are more clearer.
As for improvements - could the play bar at the bottom be minimised as an option - button on bar, at the start of each track pops up and then minimises, the same for the main options on the left, so you can have a full screen to scroll through.
