Sales Page Builder? w A/B Testing

As I reflect on the gaps in my online marketing workflow what is missing is A/B testing on my sales pages. If Heartbeat allowed us to create sales pages and included A/B testing I would have a complete solution without adding or including other tools Im using right now that fragment things and makes it more difficult. You have affiliate tracking. You have courses. You have communities. You have an order form structure connected to PP and Stripe. Give us sales page building and A/B testing (I have a couple other platforms for building webpages but neither have A/B testing) and you will draw a LOT of attention. Also, there are enough page builders out there I suspect there may be a way for you get a lot of this code already completed.
