Let's fantasize on the topic "If Photoshop can be used in real life."
In fact, it would be convenient and easy to live with. Look.
Close a child's mouth would be easier
Delivery of furniture would be a pleasure using the Move tool
The history of events would give an opportunity to correct mistakes made
One click could be removed lover
Or delete unnecessary layer of clothes on the girls
Paint the house a different color could be using the Paint Bucket Tool
