Hey Jeffrey Todd Sooey -

I think we already have this!

There's the Media Library, which you can now access through the media sidebar in a project. You can also use the project panel inside of the project and import media from previous projects if you haven't stored it in your media library yet.

Let me know if there's something I'm missing here!
