Rosalyn Hunter writes about using Composer as a stand-in word processor. I too, have used it in this fashion on OS X. I like it for various reasons. For instance, I'm quite familiar with it, as I've used it for website authoring numerous times. It creates HTML files. I've come to the conclusion that HTML is not a bad “language” to use for a word processor, considering that it already allows for basic editing features--and then some. If it isn't obvious, Composer is an HTML editor that was part of the old Mozilla suite.
