It's been well over a year ago since me and mitte scrambled to find sugar cane to make our very first map. We were greatly disappointed in this entirely useless feature.
Today, I was reading through the changelogs for the newest snapshot, and I noticed this
[Maps are] now crafted as a close zoom scale and can be extended (zoomed out) by adding more paper.
i don't understand the add more paper thing but with frames you can put maps together on a wall. There are rather big gaps between frames though. Maps now center on common points rather than on you where it's crafted. So they line up on there own.
minecarts cause a lot of unknown damage. Being able to move manually is much better than pushing and hopping in, possibly loosing your cart with out you.
that works for minecarts - but what about powered minecarts, are they "pulled" along with the minecart or do you need to push them, fire them up and hop in the minecart beside it?
edit:
i just checked - the "Minecart with Furnace" always goes in the direction you're facing while putting the fuel in - so if you sit in minecart you can't get it pushed by the powered minecart since you cant face away from it and right click :D
