The ability to be able to edit the world data

[DavidTheTech]

To be able to edit other dat files like level.dat or other dat files from different mods.
a file view to select a .dat file to edit that would be nice.

Editing world files on disk in-game is dangerous, it may break your saves, you'd better quit the world and edit through some software like NBTStudio.

That's fair enough, was just thinking it would make things a bit more efficient when doing map stuff, would a warning message help that explains the danger before clicking a confirm button?
