1 - When using together with the minimize to tray addon, two separate instances of Thunderbird run simultaneously. Would be great if I didn't have to keep the window minimized in order to see the notification badge.
2- When an email is unread, it shows both at the "Inbox" and "All Mail" folders. This is displayed as 2 new emails in the badge when it should be only 1.
