I was wondering if there's a way to create an added option to slow down the play time of the program blocks when using the debugger? How would this be done; would I just be making changes to the central interpreter such as adding wait periods? Additionally, would it be possible to add a reverse feature such that users can undo the actions of previous blocks? Since the operations are stored in a stack, is this a feasible thing to do? Thank you so much, I appreciate your time.
