I am trying to gather information about general product features or tech features that might not be the core of the product (eg: a cart is a core for e-commerce), but you would want to develop in your product as part of cool offering (eg: login with face on website, not the core product offering but a cool feature).<p>Or, what is the coolest feature or a module that you have already built in your product?<p>How do you think it would help your users? Wy do you think it is cool?
