I use TeX, but I dislike it. We need a multifont WYSIWYG
notation, and should be able to get it. And Mathematica
has far too many uses for [] for intelligibility. As I
recall, at one time Apple had such a capability.
Another beef is with the requirement for long expressions
such as "FullSimplify" and "IndentingNewLine". I can
program far faster than I can type the program.
