I totally agree with you Muhammad Mazhari; Snapchat would benefit from a tagging feature it would also enhance the user experience. I had many occasions where I was with friends and missed out on snaps; I see this feature coming soon.

However one feature which I think would be an awesome is a friends story feature where you can create a story and add your friends as contributors to that group story. This story will then feature on each persons Snapchat as a extra story with the group name. I am currently writing a post like yours to explain what I mean in more detailed.
