Visual Editor for Django Templates?
Kind of an oblique answer, but if being able to use tools like Dreamweaver on your templates is important to you, you may find you like Genshi better than Django Templates, and it's easy enough to switch your template engine. 
Genshi is an XML templating language that is one of the inheritors of the Zope TAL family. Your template file is a valid XML file, so you can open it in any XML aware tool. Personally, once I got used to using XML templates, I couldn't go back, but they are slower to process ( an xml parser has to run behind the scenes ) and they require valid XHTML in your output which can be a good or a bad thing. ( Invalid user submitted html content for example would need to be forced clean using something like Beautiful Soup or ElementTree ).
Is there a tool out there for visually building Django templates?
Thanks
