That is, when I get into that library and inspect that part in detail, I see that the power and ground pins are still power pins, not input pins. So one would think that my change had not been saved into this part.
However, if I add more of these parts to the schematic, the ERC complains that the rails are floated. One thing I have not done is to start a new drawing entirely, where I might add the same part, and observe if the rails are floated. Stay tuned. And if you have any advice, please reply. Thank you.
