Simpledit is a customizable text editor with many great features including no 64k limit on the size of files you are editing, the ability to save the text as Windows or Unix style text, a task bar to easily access each document, and a status bar with lots of useful information.
There are many editing tools to choose from such as the HTML to plain text converter, and the text re-wrapper which takes text which was previously wrapped in another program (ie. an email client) and re-wraps it so you get no half lines.
