When I say "do not go in chests" I mean "live full-time in my inventory, just like tools" - I always have a healthy square of mud, enough sand/gravel for dropping, ladders, signs, buckets, coal, torches, etc - stuff that I carry around for when I need it, so I don't have to traipse back to a chest.
I'd like several 'inventories' - like toolboxes maybe, I'd be ok with only carrying one at a time but I would like to be able to change quickly/easily from my mining kit to my building one, or a 'gardening' one
Who built the huge fucking trench that cut me off from my shit? And where is the entrance to the other side? I had a chest over there and now I have no idea where it is, and can't get over there because the stupid fucking game thinks I'm trying to fly! /fuck me/
lava can be a bugger, it can set fire to you diagonally as well as if you fall in, and it's so often under something good (like diamonds)
I often dig all around diamonds, carefully removing everything dull, even under - you can drop sand or gravel into lava to get rid of it, or chuck water on - though that will result in obsidian (or cobble if thelava is flowing)
