I’ve been thinking about this idea for a while, but I just thought of a name for it:

*Universal Undo*

It’s not a flashy name, but it’s not a flashy idea. It seems like a heel-of-hand-pressed-to-forehead simple idea. The iPhone has something like it. (Shake it like a… french au pair.) Why doesn’t this exist on the real computers? Have you ever done something minor-but-annoying:

• Accidentally quit a browser
• Closed the wrong tab
• “Learned” a misspelled word
• Deleted a file by mistake
• Minimized the wrong window
• Saved rather than Save Ased
• Overwritten a file
• Accidentally dragged an application/folder off the dock
• Like, done anything minor but slightly time consuming to undo???

Why isn’t there a Universal Undo? I realize it would probably call for keeping like everything you do in your RAM or making a constant real time backup or something. I’m not a computer scientist. But they do all sorts of other seemingly magical shit. Why isn’t there a cross-program, system-wide Universal Undo?
