would it be a good idea to introduce presets for stuff like this? bouncy, crude, slippery, whatever name would make sense. for react-spring we had 4 or 5, so that users dont need to remember what damping and tension are, but here it seems even more critical, because it's probably harder to understand what these values actually mean.
