Maybe adding the option to export the artist and the title separately is a good idea too. I remember a php code that I wrote a few years ago that divided the artist's title by the carecter "-".
RadioBOSS already "knows" artist and title of a track (and lots of other info, too), you can export it using HTTP notifications and also in the XML nowplaying file, where the info is separated by fields.
It's not a big deal (technically) to display artist, title and any other info in the Nowplaying bar, but I'm not sure if it has to be done, because:
1. You can see (and edit) most of tag fields in the Track Info panel under the playlist, so displaying the same info in Nowplaying does not add value.
2. Currently it shows the streaming title, as it's sent to the server. So you can verify that e.g. station IDs use the custom title you set in file types.
It still needs to be considered. I think a possible solution would be to simply add an option to control what info it shows: streaming title, or separate artist/title fields.
Adding artwork makes the UI looks much more fresh, so it's definitely a good idea.
I would not eliminate the audio bars, I would put them in the background with transparency as they currently are.
Another question: is it possible to add a degrade of colors on each panel?
Ah, OK, in this case this makes sense
