@TheDuke55 's idea, I want to be able to see little posts animals make about what they're doing.
I call it... FaceNook.
Nook'dIn? Idk. Lol. I just wish we could go look at a super simplified feed of posts that would kinda tell me where my villagers are. Like even if it's not explicitly saying what it is, hints would be nice. For instance, they could say "it's a beautiful day out!" Or like any mention of the weather would mean they're doing something outside. "It's shopping day!" Or whatever could mean they're at Nook's or Ables. Basically just narrow it down so they can more easily be tracked.
The app could also have cute little shout-out messages for birthdays and maybe even favors, like "oh, thank you so much to *playername* for delivering this package to Puddles! Glad the fight is over." And then puddles might comment on that like "We're ok, bestie, *playername* is totes the greatest!"
You know, it's ironic that I want this, given how much I actually hate social media.
