Small aside: I’m still looking for a framework/UI library fully designed and developed micro-interactions. Even the best ones tend to have jumps that feel like glitches.
These were a lot less obvious than with some other libraries (including ones claiming to be meticulously designed ...) and I have to extend some props for almost everything that animates in also animating out (almost everybody messes this up and it irritates me a lot, just leave it unanimated if you're not going to finish it ...).
In total I think this is a pretty high quality library. Definitely not bad!
