Minor cosmetic thing, but with all the marketplaces and PC shops which are set out as stalls, it's a bit odd to have nobody about that you're "buying" from. I guess this is true of all PC shops, but stands out particularly where they're countertops - like the Guldorand market square. Would add a nice cosmetic touch to have a few NPC shopkeepers behind at least some of the counters to seem like they're selling the goods on behalf of the owners (those shop taxes have to go somewhere right?).
Obviously not the temporary shops, the whole point of those is that the PC mans those - but the permanent ones would be a nice and I think low-effort(?) touch.
