[Zope] HTML-Kit

I have been using HTML-Kit/External Editor ( http://www.chami.com/html-kit / http://zope.org/Members/Caseman/ExternalEditor )-- a useful combination that seems to handle python and page templates well. It seems to do nothing for dtml though ( well not entirely true it lets you edit it as text-- but no colour coding or other text editing aids). Has anybody ever seen/created any dtml related plug-ins for this program?
