In reply to George.

The vast majority of e-commerce stores do not want their search results to look different than their categories and an overlay UI is in the opposite direction of that. But no images too?

These are both things we are aware of and have been working on. There is already an initial prototype merged, but we still have more to do before it is ready for production. One thing that may not be clear is that the overlay can also be opened by clicking on links on the site. So for e-commerce we can display a list of categories (in a sidebar or menu) and those links will then immediately open the overlay and apply the filtering. This way we make any discovery task on a site very fast which is why we think it can greatly improve revenue on eCommerce sites.

Thanks for your patience as we continue to improve the product for different use cases.
