Simultaneous photo sending/unlocking
Trading photos is a pain. There's always a debate about who is going to send theirs first. There should be an option to send another user your photo but that photo only gets shown or unlocked to them if they have sent one of their own to you. Both photos unlock simultaneously.
I could see the notification saying, "this user has chosen a photo to send to you through the fair photo trade option. If you wish to make a fair trade choose a photo to send them in return and we will unlock both simultaneously"
This would reduce the number of people who claim they will send their photo in return but never do, or instances where someone has no intention of sharing their photo.
Great idea for fair sharing pics
Hope from programmers also to ensure everyone is sharing his own face pic
I have never seen so many people so serious about something that is for entertainment only.
