Inbox needs either a mark all unread OR a toggle to not show the # of items on the icon

All of my team receive their Updates from monday in their email. Many (myself included) would like a mark all as read feature (like there is on Notifications) or the option to not show the count of messages in the Inbox. Many of them feel like they are missing something. Our former software, Accelo, did have this option to turn off the display of the count on the Inbox icon. Many nerves were calmed when I turned that on.
