The free extensions in vm1 grown over some years. A lot people like the new interface more and say it is faster, more intuitive to use, and cleaner. It is a matter of taste and habits.
I ran up against an issue while deploying Cookie Monster on a development site. We use a Slideshow script which was badly written in the days of JQuery 1.2.6 and conflicted with the newer jQuery used in cookie monster.
I contacted Mustaq Sheikh via their support forums and he has gone out of his way to help. They even ftp'd in and altered the sideshow script to make them work happily together.
These guys are an excellent example of how to do support right.
Thanks for making your Qualified review, it is appreciated, thanks again.
