Hello to all of the CubedCraft community!
==============================================
I would like to suggest the full WorldEdit plugin on Creative, released to Members.
Why? Well because the WorldEdit on Creative is just normal //set, //undo and //redo.
This does not called "WorldEdit", but some simple commands that we all can do with Command Blocks.
If not added, atleast consider to add all of the //brush commands, //setbiome and /gmask.
==============================================
King regards,
Jordan
