Hi @doron_levi,

I drafted as tiny example of why interfaces are useful in a [previous forum post](https://discuss.daml.com/t/rational-in-implementing-multiple-interfaces-views-in-a-template/5396/4).

Please, have a look and let me know if that provides you with some clarity. Further above in the same post, I explain why interfaces have a view.

Matteo
