There's a lot of really silly and forehead-slapping moments we've all had over the last years, so I thought it would be interesting to see what everyone has as far as tips. They don't even have to be the most efficient, just neat stuff you've incorporated into your runnings.
For example, we all started in some way or another with a wall of furnaces (I've always done 36, even in Beta… don't judge):
Of course I still have the 3x12 for massive cooking like sand and such, but I do so love this little kit on the side:
It's my slowcooker, and it's great! It takes a while, obviously, but if I'm just farting around the base it doesn't matter. I've burned all my mushroom blocks (because they were a huge weirdness since day 1), some fences and gates and a ton of other crap I accidentally made too much of.
Simple, smart. You could even cut it in half easily.
Bring your tips! Your neat stuff! Anything you're proud of or you sit in front of and go, hmm, this is nice.
