Instant Messaging (IM) — and the notifications that come with them — are horribly fragmented. iPhone users have iMessage built-in, but if you use Facebook then you likely also have Facebook Messenger, if you use Google you likely also have Google Hangouts, if you come from BlackBerry you likely have BBM contacts, and depending on what part of the world you're in, you likely also have WhatsApp, Line, WeChat, Telegram, Viber, and more all locked and loaded. That's an awful lot of beeping, buzzing, and badging to deal with. If you handle notifications the instant they come in, then it may not be a problem. If you need to go back later, hunting for little red dots all over your Home screen can be a hassle. So what's the answer? Unify them all in one folder!
