A few permit related ideas:

A "Patrol" option, which would let us set two (or more?) destinations for a permit NPC to wander between. So I imagine you'd place down the NPC, then tic the option for "Patrol" and get to place it down a second time, then the NPC would move between those two spots, idling for an appropriate amount of time at the start and finishing spot.

A "Interact" option, which would let us set a permit NPC to "use" the nearest piece of appropriate furniture. So say you place a NPC in front of a stove and select this option, their idle animation would now be them cooking at the stove. In front of a counter, perhaps they start wiping it down. They could actually sit on chairs, use stools, read books from bookcases. All of these animations already exists as far as I'm aware, it's just a case of setting up the function. Might be iffy with Lalafell, but I'm sure they can just magic out a stool to reach high up places?

And because I'm still waiting for this to be added:

NPC permits for "fun" activities. Permits that don't add a shop or any function like that, just ones that liven up the place. Musicians, Entertainers, Dancers, etc. Could even have some functionality added to them, like a Triple Triad NPC who you can set the deck of (using your cards, of course), was also thinking a Bard that you play a song for using the Performance UI and he then repeats it ad nausium, but then I remembered the legal fluff surrounding Performance being added to begin with and that's probably crossing a line... Still, plenty of entertaining NPCs you could add with this regardless.
