Undo and Redo

In the process of editing, if you are not satisfied with the current editing, you can click "Undo" button or press "Ctrl+Z" on the keyboard to cancel the last action. Similarly, if you would like to continue the last command, you can click "Redo" or press "Ctrl+Y" on the keyboard to continue the previous undone action.

NOTE: "Undo" and "Redo" functions can only implement the active action which has not been saved into the layers; once the editing is saved into the layers, "Undo" and "Redo" will be hidden like the status of beginning.
