Also not very impressed by what I saw when I tried Nice in Chrome on a "modern" Android device. It's just looks so unresponsive. None of the animations that signify something is happening works, and the keyboard blocks most of the text input modal.
I understand that Google doesn't much care if their OSes look like ass because there's no money for them in making a good design. But for a web company to have such crappy support for 5 year old web standards is just … asinine.
Not sure how I'll tackle this issue. It'll require quite a bit of consideration and probably a good rewrite of a lot of the web interface to make it artificially slower 🙄
