Just started playing this. It's worth noting that nothing lower than IE10 is supported (due to flexbox and other things I suspect) and it's javascript dependent. That results in broken stuff for around 2% of traffic depending on the audience. Also missing are a date picker and range slider, which is a pity for a UI framework. Still, I'm liking it a lot.
