The minesweeper now has flagging on mobile. It doesn't use long presses because for some reason once my phone detects a long press it seems to cancel the regular mouseup and doesn't trigger any events I could find in doing so. Hopefully the alternate solution I've come up with isn't too horrible and works on all devices!
Hard for everything not to feel futile between global, national, and personal events, but sitting around is even more futile. Other stuff will continue appearing on here, probably first the next TARDIS console on the Dr Who page in a few months. I've made a whole bunch of tweaks to the earlier models too, having had plenty of time to notice mistakes.
