GemPages Landing Page Builder

Positives - very easy to use, much more flexibility and design options than you have with Shopify's built in page builder. So the ultimate final product is much better and more attractive.

Negative - stunning wait times for assistance, and the current V7 doesn't allow you to break up any information in the standard Shopify product description (as the app description says it does) so the Product Description module has zero flexibility, which is a BIG problem for templates, since I have a serious need for this kind of function.
