We appreciate the suggestion. We have considered doing extensions for one particular framework or another... and Wordpress is certainly one of the most common.
It isn't just our extensions that don't work great in the wordpress environment... it is any server behavior and much of DW functionality in general. This is why we want to create a framework that will help you work within Dreamweaver with our PHP framework.
Wordpress is almost like another server language to take on instead of the standard dreamweaver php server language. There is quite a bit we could do and could go down that path at some time in the future.
