Thank you for your honest feedback, although it's not 5 stars.
We decided to comment below, as some of your suggestions are useful and will be added in the future releases, while others will not. Let us explain why:
We understand that your main concern is the design and layout. True, the design is important. However, the whole point of Accelerated Mobile Pages is to make your mobile pages "accelerated", right? Let us point out, that every customer can check the design at our demo site
As for the social share functionality - it as already included into the AMP extension roadmap and will be available soon. We always keep track of new features that emerge in the AMP project on GitHub, and those are added frequently.
Robson, we are happy you liked the speed of our AMP Magento extension, as it's the key of AMP technology.
We appreciate your review, and hope that diving more into the technology helps you get the best out of AMP.
As you can see from other feedbacks, the overwhelming majority of reviews are positive and our clients are happy to use AMP extension.
Our friendly support will be at your convenience if you have further questions.
