What do you dislike?
I sometimes have issues navigating the documentation. This isn't so much the writing as it is the performance of the actual documentation website— I occasionally have experienced timeout errors or glitches.
Even as I write this review, greensock.com is giving me pretty sluggish load times, so I would greatly appreciate the interactive demos and examples split apart from the actual documentation.
Sometimes stacking the products I.E. gsap with jquery with scroll plugins etc. I get a bit confused, and the proper hooks can get a bit murky, I think this could be solved with slightly more extensive documentation.
Recommendations to others considering the product
If you're doing a site full of custom animation, it's the best out there. It trumps anything built on Jquery, Moo, etc. But if you only need to animate a handful of items, save the bloat and stick with css3 and custom JS calls when necessary.
The morf SVG plugin is the absolute best thing I've seen for vector animation on the web, but I haven't purchased it because the relationship of that project's budget to the recurring annual fee didn't make sense for the site I wanted to use it with.
What business problems are you solving with the product? What benefits have you realized?
Above all, I'm saving development hours for animation on the web. I've gotten great, cross-platform animation functionality for my clients' websites out of the box, with very little learning curve.
