I can see how many vm's or sms's i've missed, as they are numbered next to the app icon. But what about 3rd party apps like FB, Voxer and others? Is there a way to do it?
The only way I've found to do so, is by using Nova Launcher and Missed It! Both are pay apps although I believe Nova Launcher has a companion app that will do the same job as Missed It!
If these interest you, I'll elaborate but if you had something else in mind, let us know.
