Following up on one of our discussion points at WM2014, I talked about the categorisation of compendium works, and the ineffectiveness of the current system approach.
Anyway, as discussed at that time, numbers of us said that we would find it useful if we could have an alternate means to display categories, I have submitted that bugzilla, and invite you to peruse it as covering the points that we need, and for you to make any suggestions that would make the proposal better, more fully functional and more broadly useful.
