Lichess is a god-tier piece of software. Nearly every time I use it I'm surprised by some new, incredibly well-implemented feature. For example, I recently discovered that if you hover over someone's username, and they're playing a public match, a little box (an iFrame? I haven't inspected yet) appears next to your pointer with their game, updating in realtime. I really need to take a look at the source code, I'm sure I would learn a lot.
