@Sharky-PI Ah, yeah, I know about the spanner, thanks anyways! but if I change it to genre, then I'd have to change it to artist when I want to see artists, and so on.
I'll try the playlist workaround, seems like it could work. Thank you!

Hello! Thank you for this great program and all the effort put into it. I was wondering if a feature like this could be implemented. What I mean is having two (or more) "collection" tabs, so that we can sort each one of those however we wish. For example, one could be sorted by genre, and the other could be sorted by artist, and the other by album, and so on. Is this feasible? Thank you.

There, for example, I've got it by genre. But, below my first "colección", I would like to have another one, so that I could have it sorted by artist first.
