@ULIBABA66 I agree with EVERYTHING you said, so i'm just sharing some thoughts about some topics you brought.
Household:
They should add more 4 sims to complete the superior line of household sims at least, it annoys me so much having just 2 sims up there and the entire open space.
Lifespan:
If they couldn't make it customizable, i'd like to have 3 sub-stages for each lifestages, representing early, middle and late years so we would have more years to experience each lifestage.
Neighborhood:
I'd love to edit neighborhoods and that would be so easy for them to do, it's like terrain edition+garden decoration+debug+outdoor items.
Color variations:
Just wishing new color variations for hair, eyes, miscellaneous skin they could give us a color wheel or saturation and brightness sliders (for that we would need the 7 rainbow colors)
Tattoos:
I'm actually living for a paint mode for sims and i wish to have tattoos in stamps section. But only tattoo placement would be enough.
Buying lots:
I just can't accept that we can't own more than 1 lot that isn't a retail one. We alredy have a similar system, why not explore it to improve gameplay?
Colums:
They could add and option to reorganize the CAS colums quantity like most gallery apps. It shouldn't be that hard...
