External Tools
Here is a short list of external programs for Minecraft that I've used and can recommend personally. External programs are not mods and generally work with all versions of Minecraft.
MCEdit: World Editor for Minecraft MCEdit is a saved game editor for Minecraft. Since Minecraft saved games contain every single element of the world the player is playing in, it has much more in common with 3D world, map, and terrain editors than traditional saved game editors.
