I can't just hit save--that just saves it to .txt,
Just thought I'd chime in (this is my area of teaching). You ONLY have to do the save-->as and choose all files the FIRST time you create an html page in notepad.
Once you saved it you can make changes and simply save again without that hassle. If you close it and reopen, you also only have to use a simple save.
It's sometimes helpful to have the notepad file saved as you html file resized to 1/2 your screen and then you can open your browser on the other side of the screen and when you save your html, you quickly click on the browser window and refresh (F5 or use the mouse) and you can make lots of changes very fast.
This doesn't really give you a suggested new wysiwyg, but it works efficiently. When I don't use notepad when teaching XHTML, CSS, or PHP, I use Dreamweaver, but it seems for what you are doing, you are using the simplest tools.
