/Undo something is useful if you made a mistake using /fill or anything else because. . . Its anoying when you do the command wrong and can't undo it! Sometimes when you do /fill x y z minecraft:air minecraft air and you forgot to do something after that like /fill x y z minecraft:air 0 replace minecraft:iron. . . Then all things you have done will be gone!
Learn to make backups.

This isn't a feature you'd just add in there – it'd take a whole bunch of memory, slow down every single command you ever run not to mention a huge amount of effort to implement… just generally a bad idea.
What they need to do is add a button in the single player menu, that makes a backup for you, and puts it in a backups folder. Possibly renames it to; “WorldName_DD_MM_YY”
sorry Sliced_lime, i guess i need to know how much things worth now 🙂 (memory and coding stuff), big fan 2 m8 with ur vids
Nice one, let's all copy our worlds, before editing them, i'm sure, this would take less space then an ingame entries for the /undo.
I'd love this– sometimes I feel like I'm playing “map maker” on hardcore with runaway fills. Even just an /unsave command that reloads what's saved on disk (without first saving what's in memory) would go a long way. /reload is already taken, woo hoo.
That could be an interesting idea. Servers already have commands to control when saves happen; the same level of control plus a /revert commands could effectively work as an undo, where we turn off saving before making large changes, and revert if it goes wrong.

Definitely wouldn't want all the extra lag of having to store large amounts of data in memory for all the command stuff I make. It'd probably have to be an optional argument at the end of the command (
Might also confuse people if some commands can be undone but not others (/setblock? /blockdata? /entitydata?) and it wouldn't really be feasible to make all commands undo-able.
Taking backups would probably be the best option for now.

Make it only the user of /undo is undoing his/her commands, without interferring commandblocks and other players.would be a shame, when it gets implemented and the first bug appearing would be a random repeating commandblock spaming the /undo entries.
Nopenopenopenopenopenopenopenope. This'd be so hard to do. The game'd need to store all the changes you made, and how would it do so?
OK OK! I get it if someone saying nope because of the time and effort would be so hard. . . So…. sorry T_T
