So far I have read reviews and heard of some of the new features of Dreamweaver CS4 and I must say they are cool, but they still do not meet the expectations I had for it. Personally I have used earlier versions of Dreamweaver and demos of current versions and one thing I believe the software lacks (which others have done so well the incorporate) is a good code editor.
I’m yet to test out the new features in CS4 but I guessing much hasn’t changed since I have not seen any reviews about changes in the code editor. There are a lot cool features for CS4 like improved Live Editing and extra Spry framework features. I hoping for the best in CS5, because I also use Netbean (6.1 currently) and I must say coding in that environment is more than decent. All the best to Adobe, and let’s see if things change in that direction.
