Congrats! Some feedback concerning the UI: * The speech bubble contrast should be higher. * The "tick" and "close" rounded buttons are aliased?! The icons are too sharp. * The button to start a chat and the title "illico" do not seem to be aligned. * Somehow, the title "illico" alone is not strictly centered :/

PS: how to write a decent-looking list on Hacker News comments? :/
