For my part, I could never figure out what katapult was for or why anybody would want to use it. The very limited documentation for it just seemed to assume that you'd see it and love it, but it seemed like a crippled version of the standard run dialogue, with bling. Unfortunately, krunner seems rather like that to me too. I'm willing to give it the benefit of the doubt for the moment because some of the problems with it are clearly bugs, but it's slow enough to use that it interrups my train of thought while doing so.
