The floating labels in input text fields are a nice finding.<p>The click animation for most elements is too strong, though, at least on the desktop. I haven't tried on touchscreens, they may be good enough feedback for direct finger touch, but they are distracting when using the mouse for clicks.<p>Is the exact highlight animation mandated by Material guidelines, or can it be tweaked? I believe a fast, simultaneous "fade" effect that made the animated circle/rectangle lighter while its moving would be enough to make it subtler and less aggressive.
