If I get a new email, it will appear on the screen when I click the top left button, and the notification light will flash blue. All good. But if I read the email elsewhere (using Thunderbird on my computer) the notification stays there even if a send/receive has been done in the meantime.
Also, once the notification has been seen, the unread emails are no longer flagged up. Is there some app or setting that allows a notification up near the clock with an "unread email" count?
