omg i love your ideas and i do think the retail system shouldn't be limited to this specific world only (Magnolia Promenade) i think it should be in each worlds, sure it might look useless at first glance but we can atleast sell big furnitures if the retail system becomes optional (the business venue is optional to add in each worlds so why not the retail system venue?)
fun fact: i think i mentioned this when i created this post not knowing it's actually possible: an updated version from this pack idea | EA Forums - 11878992 not gonna lie "Get To Work" needs a refresh
i didn't even knew you can actually sell furnitures with the "Get To Work" pack but in this case, this is the only expansion pack (i know so far) which doesn't come with new personality traits or aspirations
we need atleast 1 aspiration and i might know the perfect one:
-Running the furniture shop/market (money category)
as for personality traits:
-hardworking or superkeener
i won't delete my ideas just because of this but some of my ideas should be added in "Get To Work" if they decide to refresh this pack
i hope with both of our ideas combined we'll get a "Get To Work" pack with huge improvements this way
