First off, just so you know for next time, it is recommended that you have one topic for every suggestion you have.
Second, it is also a good idea to do a little searching before posting your idea.
Pool has already been suggested and talked about multiple times, and the devs have stated that, if they are going to make it, pool will likely be a condo game due to the stress of a physics based game in a plaza that’s going to be saturated with features.
Searching for “elevator” returns some more diverse results, but it’s still easy to find notably similar suggestions. I don’t know of any plans to remake Elevator Source in TU (though I, personally, doubt it will ever be added outside of a possible Workshop mod).
Looking for “computer” does return a lot of varying results, but this topic is still near the top. It’s a bit different from your idea, I suppose.
Customizable condo layouts are expected to be added in the distant future, as far as I know.
Also, curse you @EvKem for beating me to the post!
