Too heavy. MicroEmacs loads instantly.

MicroEmacs is small and lightweight. I port it to whatever machine I'm using, and it works nicely in a remote tty window. It doesn't need a customization language, as I just change the source code.

Recently, I added color syntax highlighting to it, and support for unicode characters.

For how long have you been coding without syntax highlighting?
