IMO the curvature it's a bit wide. I want to appeal to everybody who want to do this buttons to make the 3 mode versions: normal, hover and pressed. Or just make diferent colors. Then we can have a different rollover effect than the shinny one. I suggest if can one have skill to make a PANIC buton (red one like in the movies) but make the 3 modes , that will be funny.! Regards
