Undo or CTRL+Z does not undo a script/plugin - you need to delete the script/plugin tag from the operations list instead. Can script/plugins be added to the undo stack please?
Hi, you can kill the script operation deleting the operation in the operation stack of the Object Operation Panel; there is a red "X" in the bottom, you must select the object, then in the stack you must select the script operation and the you must click on the red "X". Bye.
