Well, I got the mod Spawner GUI and it's pretty cool, but I noticed it will only let you change the spawner in creative mode and NOT survival, Is there any way I can configure this? Please let me know!
There is an alternative. MCedit. There is no need to install mods and it is an open source program. http://www.mcedit.net/ It is a world editor, so you can edit things with out enabling cheats.
