Can we merge this?

Then I can create the next PR (for feed sidebar actions) with the correct rebase etc from https://github.com/devlinjunker/news/compare/folder+all-items-routes...devlinjunker:news:sidebar-actions?expand=1 (still working on unit tests though, so this will likely be a few more days)
