When people think of what superpower they would want, most people respond with ordinary superpowers like flying or invisibility or X-ray vision. Unless you plan on putting on a costume and saving the world from evil, many of the common superpowers are really only useful for causing a lot of mischief.
I mean, being able to walk around invisible doesn't have a lot of practical legal uses. Nor does X-ray vison. Nor a heat ray. At least, not unless you plan on having a lot of barbecues.
The kinds of abilities you do want are the ones that aren't as cool, but are more useful. Like being able to deflate your legs to fit into an airplane seat. Or being able to clean something with the wave of a hand.
I think if I had a superpower, I'd want the ability to save. That way, if I have a big decision to make, I can just quickly save, and later if I realize I didn't like the outcome, I can just reload and try again.
Didn't like the chicken? No problem. Just reload and have the soup instead. Fell down the stairs and broke your leg? Again, no big issue. Just reload and take the elevator.
