So, with Smash Bros, if you are viewing your friends list and they are playing online there will be an "Available to Play" notice right in your friends list, which you can use to join your friend quickly.
This is a similar feature which was in the 3DS. Is this now supported for all online games? I noticed this worked for Watch Dogs as well. Do the games need to support this, or is it OS based?
This small feature would be very handy for MK8
