I use PHP Designer. Dont' let the name throw you, it's not just a PHP page builder. It's got TONS of useful features (such as a library that has documentation on each and every tag for HTML, PHP, SQL, CSS, and XML). It also has a built-in webpage previewer, so you can preview your work without having to open up a separate browser. Unfortunately, it's not all that WYSIWYG.
For ultimate WYSIWYG (that's free), check out WebDwarf. The only things I have against WebDwarf, is that it creates alot of geometry and object files. So, if you're using a free website provider that allows you to upload 1 file at a time, this can be a pain in the butt. But, if you're allowed using FTP, or multiple file uploading....you're good.
In Bluevoda threre is no commands for saving or opening pure html files. When you preview your page in browser Bluevoda produces html pages to folder c:\documents and settings\windows username\local settings\temp\preview. From there you can take ready html files.
If you like to use Bluevoda's easy publish and ftp functions you need to buy a Vodahost account.
