This plugin has its shortcoming, but so does every other plugin in development. Some functions aren't working, some need a little tlc and styling could use some help, but negativity aside, this is a great plugin. This is the only plugin that does everything in one shot without needing integration from others. The backend is well laid out, options are plenty and it just works.
A few more releases it will be the best plugin for selling photography period. WP_eStore is a garbage plugin, horrible support, and one of the worst I've ever seen in security. This plugin could easily satisfy photographers without relying on NextGen and eStore. I give it 5 stars for it has a solid foundation.
