This new version is really a big improvement in term of UI. And the "music explorer" tab is great.
If you are willing to go further later, here are some ideas picked from a foobar skin:

- in the screenshot here you can see buttons for the "thumbnail browser", which allow to quickly switch between genre/artist/album view
- and there is a search/filter field on top of the list, it's great when you want to find quickly a specific genre/artist/album
- on the main panel, when there is only one artwork/album for the current view, the "expanded panel" is expanded by default.
- and a progress bar is displayed under the playing track
- In the bottom, you can see a menu which appear when you click on a button in the control bar, which allow to randomly select and play xx albums / xx tracks / xx tracks from a specific genre / a genre / an artist.
-And when you click on the cover on the bottom-left, it locate the playing track in the main panel and on the thumbnail browser
