I'm going to have to admit here that I have NO idea what the ADDT was. I was late to the PHP party and really my only experience with Dreamweaver PHP Extensions is with WA products.
What exactly does this do?
I've installed it, I've looked at the Puzzle icons, but I'm a little unclear what it's intended to accomplish.
Does it help me reuse previously created pages in new pages?
I'm feeling a little stupid, but I'm trying to give it my best shot.
