I am more stunned by the tone your response. Why are you implying there's a "struggle" or "fundamental problem"? Sorry but your language is very condescending.

Sometimes it's easiest to hit Cmd+Z a few times to check out how something looked at an earlier stage of a change. And then it's easy to Redo everything back to the current state. Rewinding changes back can even jog your memory as to why you did something. It's fast, simple, and effective. What's so bad about that?
