Right now, Web Developer Toolbar lets me live edit HTML in the browser. I'd like the same feature, but instead of editing in the browser, I want to edit the actual html file. So, this would be some sort of "live edit mode" where open a url to your local html file, and any edits you make to the file get applied in realtime (just like the Web Developer feature). It would be nice to use my regular editor (and the true html source file) instead of a browser text field. I suppose support for CSS could work as well.
