The behaviour of clone has also change; instead of passing the whole instance to the constructor, it only passes the attributes. Could be worth noting for people who are upgrading (I hit an error because of that) :). Otherwise, great job!

Yup, can simplify code for wiring together views a great deal and promote decoupling between them.
