To me this is an improvement. I agree that it is an improvement that Plot::plnr is not shown for complex numbers (only for symbolic expressions), but why wasn't a new, separate message added for complex numbers/infinity (it could be off by default)? And why isn't the new Plot::plnr on by default? Trying to plot a symbolic expression is almost always an (unintentional) mistake. Szabolcs
