Well, I've only kicked the tires a little bit, but, I had to take a step back and appreciate how great this is. Sure, editor enhancers like Swiss Knife or Hydrogen, etc. are great. But, when you strap-on something like Oxyninja Core, or the amazing CSS mastery of Design 4 Fun Unlimited Elements which brings unbelievably well-designed and coded components or elements (blocks, sections, etc.,) You'll feel like a kid on Christmas morning.
Thanks to JoAbear, for providing these amazing resources, he was fast and professional and you shouldn't even think twice, BUY SOMETHING.
