maruseru: Does anyone know whether the author of kombilo, Ulrich Goertz, is still around? I've patched kombilo to include a rather basic problem-solving mode, plus some shortcuts to make it easier to enter problems, and support for the proposed problem type and difficulty/rating tags. I've sent the patched version to the author a few days ago but didn't get a reply.
By the way, I'm hacking on Mac OS X, so there's no Windows installer of the new version - I was hoping that Ulrich Goertz could provide one, should he choose to accept the patch.
