I wish there would be more interaction with Isabelle, especially as a mayor. I don't waltz in every day asking her how the town is or what project I should plan. I wish on random days she'd call you up and say
"Umm, Mr. Mayor, we have an issue! Please report at the City Hall! W-When you can!"
There could be a villager with either a little complaint or such, like
"Mayor, there have been some tricky folk burying pitfalls! Normally I'd be fine since I'm "rough and tough" but I fell in about 3 the other day! could you do something about this?"
And then you and Isabelle could hunt down like 10 buried pitfalls. Or there could be issues with like, beehives, or heck even Wendell annoying villagers for food. Or even Gulliver passed out infront of someone's house, Katrina's "focus" being messed around with. Iunno I'd love it if Isabelle were there more often to explain things about the game, such as the Island which some people don't fully have a grasp on.
It could be once a month so then they'd have it sparingly, and you'd never be ready for it, as unlike normal town events like Festivale it'd have like 50 scenarios to flip through and it'd randomly occur after 30 days.
Just ANY WAY to get her to be more active as a character, she's a really important character as its assumed she's more of a mayor than you, but it's like how barely I go to Kicks or Harriet.
