Looking forward to seeing what you say.
It has tabbed file viewing so you can easily switch back and forth from your external CSS file and the HTML document.
Some people like wysiwyg editors because you can produce lots of pages very quickly. But I found by making a simple php script, I can put the code for the layout in one file, read in the content for all the pages from another file, and have all the pages created for me in pure HTML in seconds.
