The same way you can drag nodes in the hierarchy view to change if it goes above or below another node, it would be very useful to be able to do this inside a state or timeline. Just for organization purposes, it would be specially useful for timeline properties. For instance I want all properties ordered by the length of its animation. So the shorter animations comes first, then the lengthier ones. Currently, if I mess up the order I need to delete the properties and add them again in the correct order. Similarly, being able to drag a timeline or state from one controller to another would be great.
