My friend is advising me to mention that my editor doesn't insert extra crap like an HTML WYSIWYG editor would (meta tags, whatnot). Every piece of code generated for the rc corresponds to something the designer told it to put in there.

If you wanted, you could use the program to start your theme, and easily go in there afterwards with a text editor and patch things up, whereas with an HTML editor you usually need to use the same program again.
