In settings for mail, would like a toggle option to default show "To" details instead of having to click arrow to display them. Now that I have email aliases, I would like to know at a glance which alias these emails were sent to without extra clicks involved.

I really like the email@email.email with the date and time displayed underneath that is added to the "To" details when you click the "v" show details button, but would be so much happier with it being automatically displayed by default.
