Show Folders and nesting for Playlists in Menu/Sidebar

It’s great to have easy access to all my playlists in the Sidebar/menu, however they currently are a long list of playlists without any organization besides sorting. It would be great if the sidebar showed the folders and nesting of playlists, so it’s not so cluttered, and easy to find the playlist I’m looking for.

YES!

I have a huge amount of playlists and the folder system is absolutely necessary. Particularly as I make roon versions of streaming playlists so many are duplicated.

The fact this folder structure is ignored by the sidebar is irritating.

Also - you can’t view folders at all on my mobile devices. Navigating playlists on an iPhone / iPad is very difficult.

this would be amazing PLEASE implement this
