Actually maybe we're both misunderstanding each other. I use Dreamweaver on occasion, but without the preview window. It's not accurate and you're better off just previewing in a browser window or three anyways.
Anywho, the OP might look into the latest version of BBEdit from Bare Bones Software. It has FTP, HTML syntax highlighting, and some semblance of project management with a drawer-like thing that contains a list of files with which you can switch to and fro (which was absent in the previous version). Plus it's BBEdit, which has been the text editor of choice for many different languages for several years (outside of eMacs, vim, vi, etc). I think an educational license is $50.
edit: Actually the latest version is being marketed as an HTML/text editor. I guess they made the newer version with web developers in mind.
