That's the first thing I thought and it's mentioned in the readme file itself. I don't think I'd ever want to use this tool. Every keystroke could be an arbitrary command, and I wonder about the performance of commands with a lot of I/O or processing. Conceptually it's really neat and I get it, but practically I find things like parameter completion in Fish much more useful.
