nothing else.... pico..
if ur feeling saucy you can give vi a try. Its a great editor, but extreamly annoying when your first trying to get used to it.. However, if you want something that will type the tags for you, you can try gnotepad+. Obviously dosn't have a lot of features, but it types tags for you.
i wrote my own for windows, that i like very much.. Im too much of a pu**y to learn C, so i havn't made one for linux yet.
