The other day I downloaded the trial version of Adobe Dreamweaver CS5, to see what the new version offers. I was pleasantly suprised. I currently have Adobe Dreamweaver CS3 and decided not to upgrade to CS4, but after downloading the new version, i will upgrading to CS5 very soon.
Here are the new features that really make this a quality WYSIWYG editor:
So all round I think it is an improvement to CS4 and is definitely worth the download. Go and get your free 30 day trial at www.adobe.com . Remember you need to sign up with adobe before downloading any trial software.
