NPC stat blocks of the 2024 variety auto-populate the senses section with Darkvision 0 ft. This alone is pretty useful, given almost everything has Darkvision now--however, there is a bug where if you delete the "Darkvision 0 ft." text but leave the field blank (i.e. for the rare creature that has no special senses), if you then close and reopen the NPC sheet it re-populates the field with "Darkvision 0 ft." It would be better if the senses field only auto-populated when the sheet was first created, and not every time it loads.
