You can already do this now with an amazing free plugin:
Would be awesome to have the possibility to map domains to pages / custom checkouts made with LaunchFlows all in 1 WP installation.
So let´s say you have x products for which you would like to have each their own Landingpage (own checkout flow) and their own domain.
Product 1 > www.product1.com
Product 2 > www.product2.com
Product 3 > www.product3.com
That would be a killer feature I think!
