idea — an app that literally won't let you open trip pics until the trip's over (unlike snap where someone always opens early)

ok so you know how on snap there's always That One Person who opens the pic the second it lands, even though the whole group silently agreed to wait? happens every single trip, no matter how many times you tell people to hold off. so i had this idea — a group photo app where everyone just posts pics the whole trip like normal, but nobody can actually open and see them until the trip is marked as done. not like a "please don't peek" honor system like snap kind of relies on, actually locked so even the person who always opens early literally can't. then when the trip's over it all unlocks at once and you go through everyone's pics together for the first time instead of everyone seeing them trickle in one by one like a normal group chat. wanted to ask a few things: does your group actually have someone who always opens snaps/pics early lol would a real lock feel good or would it just annoy you not being able to check your own pics should it unlock based on a date you set, or does someone in the group have to manually end the trip not building anything yet just wanted to see if this is actually a want or if it's just me who gets annoyed by this
