Because I have a dislike for non-resource routes, I started thinking whether perhaps it might make sense to split the projects controller into the public and private part (e.g. projects_controller and admin/projects_controller); the public part would only have the index action as currently, without authentication on it; the private part's index action would be the current "list" action. this way we would have a clear separation of public / private, as well as nicer routes. I'm happy to accept as is for now, but perhaps have a think about this if time permits.
