I've had the chance to revisit using WA extensions recently due to some projects that have come up and I feel like I've gotten "over the hump". I'm starting to see and understand the power and usefulness of these extensions. I was definitely speaking out of frustration from my previous post, but it's all starting to make sense now. I've crossed over and become a fan :)
My only suggestion to WA would be to create the documentation with a complete novice in mind. I know the documentation is fairly straightforward, but I did have some issues going through it and there were things like inserting the dataassist behavior into a form that I didn't see referenced. Probably because it seems very obvious, but being completely new to Dreamweaver I'm still learning my way around the menus and setup.
Anyway, just wanted to post a little bit of positive feedback because I think it's definitely due.
