My students have pointed out that if they try to make any edits to their images on the editor there is no way for them to hit an UNDO if they make an error like accidently erasing a pixel. This would be a very useful tool in the editor.
You can use CTRL + Z
Thank you so much. I didn't even think about a shortcut like that. I just assumed it was left off the design. This will make them very happy.
