For aliases, convenience functions, and fancy widgets, my philosophy is one word: wait. I make myself go through the trouble of doing it the usual way for a little while. This way, I usually end up with much more domain knowledge and a much more elegant solution than if I'd rushed in to make things easier right of the bat.<p>For example, I don't have `alias gs='git status'`. Just `alias g=git` works great, and git has its own awesome alias system with tab completion that gets me the rest of it. So instead of `gs` I type `g s`, and I get tab completion on all the flags.
