We've got a minesweeper minigame in mining cave-ins, right? (At least if you're as retarded as me and do like mining without support's). But where is flags to mark dangerous tiles? Jorb? Loftar? Anyone? It is very important, I'd call it a critical bug that needs to be fixed immediately. Please fix.
Like this, but placed on the cave tile itself.

Ye, that's probably all. Move on.
P.S. My head hurts from all those boulders, please save me.
