I have to say I couldn't of thought of a better list my self! I realize it's so hard to not make comparisons with the sims3 and things like CASt which I love and miss so much in the sims 4. That being said I would love if they added more patterns to walls floors and furnishings. I feel like everything is so plain. Where are the polka dots, chevrons, stripes, and just fun and funky patterns? I need patterns and more yellow would be great like doors and shutters. And, what is with the lighting? It's so crazy how I can have 3 of the same curtains (or anything else for that matter) in the same room but they all looking different colors? It's just bland I think. Half walls are a must! I never realized how much I used them in the Sims3 until I couldn't in the Sims4. Adjusting terrain would be wonderful even just a little. everything is so flat lol More stairs types and ladders would open up so many more design styles. I would also love more medium sized rugs. I feel like they are either HUGE or tiny and most don't even fit in my rooms! I do like a lot about the Sims4 building options but like many other I feel like so much is missing. Thanks for giving us a place to voice our options on this :)
