One of my long-time favorite jailbreak tweaks for organizing my incoming notifications is Priority Hub, but the tweak was never updated to support iOS 10. If you’re in the same boat and miss this classic tweak, then you might want to try a new release called Atmos by iOS developer Antique.
After you install Atmos, your notifications are grouped by app both on the Lock screen and in Notification Center. With this sort of organization, you can focus on what’s important rather than looking at a chaotic menagerie of mixed notifications.
