I think this is a bad idea because it hides the complexity of Limitations. "Laser Pistol (-2)" sounds simpler than, "OAF (-1), 6 Charges (-3/4), Beam (-1/4)," but it doesn't tell you what the restrictions actually are. Players might also want similar powers with different Limitations, and then the GM has to keep track of, "Tom's Laser Pistol (-1)," "Dick's Laser Pistol (-2)," and "Harry's Laser Pistol (which is different from Tom's) (-1)."
