Hi

If not already existing, I think that it would be great to have some sample pages showing all "live" all possible animations & transitions at a glance.

When I'm looking to add some animations to my website, I spent a lot a time to testing some .. before choosing the right one

Just an idea.

It will be difficult to implement this functionality for multi platforms (Windows/Linux/Mac), because animation preview requires browser integration, but you can never be sure a certain browser is installed on the system.
