Library of UI animations for prototype mode
It would be great to have pre-defined animations in different design languages like material design so when we are previewing the prototype we can also preview the actual animations that will happen for lets say button. it would be great to enable people to develop such animations and share it with others so they can download a "Material Design Animation Kit", further, develop/modify it or just start using it to bring their design to life.
this will obviously help with more satisfied customers, and developers where they have a common animation design language both beautiful and technologically implementable and standard.

A library of ready made animations, transitions, micro interactions, loading effects that can be applied to elements, components, layers or groups - so that you don’t have to build or simulate the effect over several art boards.
These would be inspired by popular transitions, effects and interactions usually used in development.
Such as grow, move in from the left/right, fade in, parallax, cascade in...
This would make it quicker to prototype and apply commonly used effects for loading pages, hover effects.
