I've always had the impression that UR was an internal tool that was made available as - this is what we use, maybe you'll find it useful. I've often wondered, if UR is used internally by Kinook, then how do they deal with the "short-comings" that we see.
As has been noted many times in this thread, UR is a stable working program and it appears that support and development will continue (at a slower pace ?).
