Undo actions

[DevSven]

I previously asked how to save a world but something that came in my mind when I saw Worldedit is a undo function. Does anybody know how to do that in a simple way?

Create a List that stores what has changes(Block, TileEntity, BlockPos, etc). And make sure that it stays in order of what happened, cutting it off at some point. And then just revert back in the list.
