Easy Duplication of Apps

It would be great if there was an easy way to duplicate an app from one client's account to another. In other words, if I created an app that multiple clients wanted, I could copy it and use it across multiple accounts/dashboards without having to rebuild it all over again.

This would also help me "sell" Knack to many more customers, as I could create apps for a specific niche market, then clone them for multiple customers.
