Thank you, this is really useful — you nailed the biggest flaw. You were right that there was no downside to letting it sit, so a run never truly ended. I just pushed an update: now the pot can also go COLD, so if you neglect the heat it spoils and the run ends (a "went cold" fail to match "burnt"). It makes the green band matter in both directions. I also gave the different spices their own little sound so the beeps stop feeling repetitive. Thanks for taking the time to write this up!
