Though, I have been adding some new “ready to go” UIElement types, such as the “AnimatedFoldout”, which you just use as you would a a typical foldout comes animated with no additional coding, minus some exposed properties to adjust the animation to your liking. I do intend to add more of these as I go along.
This package began simply as a small collection of helpers methods I created across my last few projects to make animating editor elements much easier and finally put into a single place. I continue to add to it as I go along but decided to put together several examples and wanted to share them.
