Temple Reservations
It used to be that if you only knew a person's first name and the first initial for their last name that you could reserve the name do the temple ordinances for it. For example a census record said that a married woman's name was Agatha H. Jones wife of Henry Jones, so one would enter her as Agatha H. Or you're looking at a very old christening record and you can see that the first name was Josephine but you could only make out that the last name started with an M, you could still enter Josephine M. There was no problem reserving ordinances for Agatha H. or Josephine M., but now the system just greys it out and won't let you reserve because you've used an initial for the last name. As this used to be fine, it isn't obvious to the user why they can't reserve the ordinances. It would be nice if this could still be done like it used to be.
