I'd like to propose two new layouts for the 'Now Playing' list.
First a compact layout that combines Title and Artist in one line but in different colors so it's easier to distinguish
It's already possible to do this with a virtual tag just needs a color setting for the Artist.
I think it makes a good use of limited space.
Second is an album art layout, which shows the cover for every track like so:
This also uses a different color for the artist name, which in this case i think would look better than say a bold font. The color would of course have to be skin dependent. I like this layout the most because it provides the most information in a very readable way.
