There is a number of improvements I'd like to see to the artist view:
* The most important improvement to me personally is instead of listing the albums in a single long line that needs a scroll, show the albums in a grid. Right now the albums 'on page 2' (ie requires a scroll) are a lot less likely to receive a random play than the ones showing 'on page 1'. Showing the albums in a grid instead would fix this, as well as give the view a much clearer overview.
* Allow a tag bellow the artist name when expanded? I have a custom tag on all my albums indicating the country where the artist/band originates from. I would love it if I could show this here.
* Group the albums in the expanded window by tag. I would love to have the albums grouped by Studio Album/Best Of/EP
* Allow a 3rd line below each album, I'd like to show the album rating here.
Here's an example of how it would look like (it's still missing the album rating though)
