Or F3 gives you some number between 0 and 3 which would tell you which direction you're facing if you can be bothered to remember what the numbers mean. Which I can't.

Or there's /compass, which just plain tells you a direction, but I'm not sure whether that would be an extra mod.

/getpos is already enabled, and has been for some time

F3 only fills the screen if your resolution is a bit low (took me months to get it right)

oh, and redstone on the floor (on just one block, so it looks like a x) always points the same way

It used to be on the Cobblestone minecraftwiki page but it has been removed many times as discussed here it seems :

Saw a screenshot a few days ago - I prefer it on teh mine with mobs off anyway I think.

While I'm here - what am I supposed to do with this?

Yeah, I prefer the mining/building with only the threat of lava and heights that can kill you. And probably water, if there's enough of it.

Oh and Drew. But he's a cunt. (nod)

No idea what that is, but I think someone alluded to it a few hundred posts back - is it supposed to be a mob in there, but 'cos they're turned off it becomes one of the animals? Don't know why it's on fire or in a cage though.
