Myz shell uses artificial intelligence and fuzzy matching to show me a drop down emax like experience for my history that i can then run. It integrates in a non conflicting way with omis shell, so i have mc fly and om o mis shell working together. What you can do is you can type a part of a command and hit control r, and this replaces your control r with this,. Like full screen select mode that'll show you all the stuff it matches. And it doesn't have just be the beginning. It can match in the middle of strings a command. Which is fantastic.
