The current components are pretty static, once rendered. Animations (in addition to the Notification's fade in/out) would bring some zing to the UI. There are also numerous usability gains in animating with taste.

How about provide features similar like Flex, state, transition and other effects. Flash has long experience on animation, hopefully their thinking of Flex can help

This would be nice. Like they have done it on jQuery.
transition effects when removing one and inserting another component or layout (switching views) would be also nice

Agreed. As the last weeks custom demo with some scroll (+other) animations showcased, subtle animations can really add to application usability.
