Very nice, but not a stitch on LyX's math editor [1]. Especially good are its user-defined math macros (scroll down to point 6 in [1], or look at this video [2]); you can even define different versions for the output and for editing. Entering macros (both built-in and user-defined) and positioning your cursor in the arguments can be done with keyboard or mouse. Unfortunately LyX tends to get dismissed a lot because long-term LaTeX users naively assume that it's just for beginners. Ironically I think you need to be a fairly advanced LaTeX user to start with before you can use it effectively.
