What are some awesome things you guys want to see added to MineCraft?

I myself would like a desert biome. It could have oases, caves, and a lot of spiders and scorpions, which would be a cool creature to add.

Trapdoors, NPC's (ones you can talk too)
guns (official)

I wouldnt mind some npcs. I saw a mod where it added wild ones, and friendly ones. Maybe even give them small quests like "gib me bacon I gib you a piece of iron".
