I would have to agree about CFE although I used it in Sims 3, but that doesn't mean I liked it. I would prefer if they came up with a way to adjust walls by room, preferable giving us an arrow, so we can just drag it to the height we want, like the roof height adjustment and if they could do the same thing with foundations that would be awesome!
I would also like to see scale-able dinner tables, so you can place it then drag it out to the size you want.
I just have to say that I have heard a lot of people complaining about Sims 4's restrictions, However I have to admit that some of the new features are excellent. Being able to pick up a room and move it or grabbing a room and changing the size without having to tear down walls and building new ones. The roofing tool is better, we just need more types. Being able to move the whole house is great. Adding a foundation after the entire has been built is awesome, just need more control over it and be able to use the wall treatments on it, instead of being restricted to a few styles.
