Should this be part of Gin?

Hi @saschaeggi! Wasn't sure how much you'd want to incorporate support for specific modules (e.g. Moderation Sidebar), but I'd be happy to see these changes—or some version of them—become part of Gin. Glad to help however I can. Just let me know how you'd like to proceed. Thanks!

I think that modules should ensure compatibility with popular admin themes, so it's probably more likely that this becomes part of (or sub-module of) Moderation Sidebar. That's probably no going to happen, so we'll just settle for the status quo 🙂.
