Calibre 4.0
There have been complaints about the UI since forever, and the developer is well-known for bristling at any constructive criticism and telling people to either accept the way he likes things, or simply don't use the application. Consequently, I am surprised that no one has forked Calibre, even if it was just to kept the backend but simply overhaul the UI.Something that I would like to see in a future version of Calibre (or a fork) is news-download recipes changed to a plugin system that can be updated separately of Calibre itself. It is not ideal that if a news recipe becomes obsolete due to changes on the respective news website, one has to upgrade Calibre to a new version. For users whose distros package only a certain version of Calibre, it would be nice to continue running that distro-supported version but simply be able to update the news recipes from within the Calibre settings.
