Additional Browser Sort Criteria

I’d love to have additional criteria that can be selected for a multi-level sort of what is displayed in the browser. Specifically, I have a ton of non-commercial recordings (marked as bootleg although most were made with the permission of the musicians). I would love to sort so that all of an artist’s commercial releases are displayed first, followed by the non-commercial/bootleg. Additional tweaks like sorting bootleg studio outtakes ahead of live shows, etc. would be appreciated, but maybe down the road if not able to provide all at the same time.
