[Suggestion / Feature Request] Ability to sort songs ingame using custom folders

[unqltango]

I really like the custom song folders feature, it is much easier to organize songs to different folders.

it would be awesome though, if I could move the songs to the folders in game too.

Use case: I download a couple of songs to the CustomLevels folder. After playing them I could just throw them to my custom folders to add them to my folder/playlist structure. They would physically moved to the proper folders.

Maybe with an optional "copy" option so I could place the same song in multiple folders.
