Big Bugs

I just made a list of the biggest glitches ever (not all glitches, but things that would be good if may be fixed). And sorry for my english if I wrote something wrong.

• Some farlands effects still exist.
• The world is not infinite.
• Redstone is dot, and not a cross, like in Beta
• You can't place pumpkin in mid air, like melon
• You can't use bonemeal on nether wart
• You don't have to put lava somewhere to grow nether wart (like water for wheat, potatoes, etc.)
• BUD powering still exist.
• Lighting glitches are exist.
• Minecarts in the same position still boost each other
• You can build on the top of the nether.
• You can break endportal BLOCKS with placing water/lava on them.
• You can hit entities sometimes throught blocks.
• Ways for X-ray machines still exists.
• There's no /playerdata command, just /entitydata.

Fell free, to pust big bugs in the comments!
