Undo / Redo Changes

1. Select the object. You can select an object on the Canvas by simply clicking it. This in turn will display the resize and rotation handles. 
2. Go to the Edit Menu and click Undo / Redo. In the absence of a selected object, the Undo / Redo will cease to work. 

Irrespective of the type of the object(Image, Text or Shape), Undo / Redo is available for all the object types.
