Take back control of your notifications
Hub++ is a significant upgrade to the default BlackBerry 10 notifications system. Users can drill down into incredibly specific notifications based on e-mail sender, subject line, and priority, and activate a variety of LED, vibration, and tone notifications.
Blanket notification profiles can be set for each e-mail account individually - even with pop-up previews of messages if you like. Hub++ is great for people who get a lot of e-mail and regularly receive high-priority messages that needs to be addressed immediately. The biggest downside here is that Hub++ has to stay open in an active frame in order to work.
