Disable animations?

[damienzhang]

Thanks for building this amazing app and giving it away for free. I'm very interested in using it to replace Workflowy, and one thing I've noticed is that Zavala feels a little less snappy due to the animation when a new item is added to the outline. Workflowy creates a new bullet instantly, and it's very satisfying. Is it possible to have a switch in Zavala to disable or speed up animations? Bike, for example, has such a setting.

I've created a GitHub issue to keep track of this feature request for future consideration. #159
