New: Multis!

There's a new creation type: Multi! Please find it in the Holder category.

A Multi allows one person, or several people joining together, to move things on a given setup. This can be anything you can think of: tabletop or dice games, playing cards, an array of creatures flying above a nest, or any use you imagine. You can click on an item to change its state or trigger its behavior, and drag an item to move it within the Multi. Static compositions with no movable parts can also be created.
