'Date Modified/Added' playlist columns
I have a non-trivial music library, and thanks to good music I find on bandcamp I'm constantly adding to it. A problem I'm having is a lot of things are often lost within the Library playlist's 9000+ entries.
Could there be a way to easily add another playlist column option that would detect the date an audio file or its directory was added or modified (might lead to some odd behaviour with modified but whatever), so the latest stuff I add to the library bubble up to the top? If so, where in the code would be the best place(s) to add this feature? I had a look through the source and obviously since I'm unfamiliar with this codebase it's easy to get lost.
Is this place just dead?
