A Web-based HTML Editor

I like web-based applications. You don't have to install anything on your computer to use them. They're usually free, too. So, I have created the world's first web-based HTML editor, here: http://www.advantage-computer.biz/tools/HTML%20Editor/. Unlike other free HTML editors, it gives you hints while writing your code. It also color-codes your HTML. (Although, currently, the color-coding feature only works in Internet Explorer.) There is also a real-time preview displayed in the lower half of the page. You can also save your code by clicking on the disk icon at the top and to the right on the page.

The editor uses JavaScript to provide the code hints and color the text. It of course also uses HTML and CSS. The buttons were created in Adobe Flash.
