Some of these are genuinely nice. I really like the action slide-out, the wall reveal, and the slide-off reveal.

Unfortunately for a thing whose core job is polished UI, there's still quite a lot of polish needed before I would be willing to implement any of this in my UI To name a few : - the swap icon state theme preview switcher cascades the element brightness rather than fading them together. - The confirm reveal has something wrong with the spring every third or fourth click, which is strange - Cards: the stacked deck cycle. When you click Next, it doesn't draw the top card. - The shared element expand option: when you minimize, the spring dampening pushes the components outside of the container. - Swipe to dismiss causes the container to temporarily show a scroll bar.
