• The mailbox now sorts the most recent email at the top like most normal mailboxes
• Better mailbox handling when the subject is insanely long.
• Added the subject to the top of the mail you're reading in case the subject is really long.
• Fixed a minor mail bug where if you deleted down to one unread email, it would not mark it read, nor disable notifications.
• Fixed a bug with the animation of small particles.
• Optimized some calculations that made things faster. Probably.
