Ok, I'm trying to explain it a little better. In the right panel, I get title information from the currently playing album, or whatever. Then comes a second time title information (2) for displaying the information about the current song of the album.
Now it would be ideal if, for example, I could click on the original artist (Iggy Pop - Lust For Life) and I would see the album in the library.
So the singles could be displayed to the album (Through The Looking Glass), to the singles the albums and much more.
So far it only works for the artist and the album. Either you can view the filtered library or artist information.
I would wish I could expand each of the seven possible fields of the title information with a search string for the filtered library.
