An improvement I would love to have is the possibilty to include the parent folder’s name  of the current folder in the playlist name. This would allowed to have, for example, Album and Artist in the playlist title.

Thanks, that’s a nice idea. Will be added soon.

I’ll just wait for a while, in case there are more suggestions, so that I can add them all together.
