Windows 8 People Groups

Hey Guys,

So one of my favourite features on WP8 is groups, i love being able to see all my family updates or messages from my clients in one place...So simple but so great

My question is can i get the same function on Windows 8? Is there a build in feature for this or a 3rd party app for this? Id love to be able to do the same on my surface and desktop.

At the moment i pin people in groups to my homescreen but would love to have in all one place.

Thanks guys
