Show noon and midnight as 12:XX A/PM instead of 00:XX A/PM

Nitpick, but it seems fields for datetime show the times of midnight + XX mins or noon + XX mins as 00:XX rather than 12:XX [A/P]M.

This is inconsistent with the time representation in the calendar display, and is otherwise not how time is conventionally represented.

Will try to update the post with a screenshot in a few hours.
