The Undo Button

I once deleted 47 pages of work. Then I pressed Ctrl+Z. Poof! It all came back! I literally cried tears of joy. I've never felt more powerful.

Ctrl+Z is like a time machine, but only for mistakes. I'd use it on my life if I could. "Ctrl+Z, delete 2020, Ctrl+Z, don't eat that gas station sushi."

The Problem

But Ctrl+Z has limits. I've pressed it so many times I've undone things I MEANT to do. "Wait, I wanted that deleted! Undo the undo!" Ctrl+Z can't help me there.
