It would be cool if they added a Xray vision command for worlds that have cheats turned on. Just type /xray and all stone, dirt, and sand becomes transparent, leaving dungeon blocks, ore blocks, and bedrock visible. Lava and water might become semi-transparent, like they are see-through but have a red or blue tinge to them.
Sorry if this is 12 years late, but imagine you use xray, right? And you're in a server. You see diamonds on the xray, so you dig to it, but the moment you mine the block in front of the ore, exposing the ore, the diamond ore instantly turns into a copper ore! That is how they prevent xray in servers.
