Nvu - FOSS WYSIWYG Web Editor

Nvu - The Complete Web Authoring System for Linux, Macintosh

Nvu (N-view) is a WYSIWYG web development application that makes it pretty easy to create and edit web pages (and other).

It is Free and Open Source. It's based on Mozilla's Composer. I've tried it out and it seems to be pretty good.

My only major complaint: Tag view needs to expose both the opening & closing element tags for better cursor positioning and editability. However, I don't know of any FOS app that does this...
