When entering other's profile you will see the Mutual friends between you
Preview Imagie:


When clicking on it, it will show exactly like on managing friends but only with the mutual friends between the users.

I'm not a big fan of such a feature to be honest. I don't think this would improve the friend browsing experience much for me atleast.
That being said I think the answers given in similar suggestion topics listed below also cover this topic.

It's a No for me mate, sorry.

No from me too. i dont want these facebook features to this site.

You already have the friends function
so why not knowing whose the mutual friends with the people you meet?

You can just check it yourself, looks quite unnecessary, and as people named previously, nn more facebook features ^^

I disagree with you, so i'll keep bumping untill locked by paul's decision.
I think if you already have the Friends feature, so this 1 line could add alot, after all.. this is a forum.
