Feature Request: Custom Bookmarks/Lists

[pugboy1321]

I've found the Starred feature key to my use of the app, and I'd love to someday see more flexibility for a bookmarking//saving system to pair alongside it. Kinda like the standard starred list, with the ability to make custom lists to bookmark/save articles. For example one could make lists for things like "Read Later", "Archive", "Project Ideas" and such.
