We need it

27evrn1ol1f9​ if you click on the interior door, say the bedroom for example you can indeed lock it for privacy from other Sims like you can with exterior doors, including pets and household members. You can also remove shoes indoors. This was originally part of the Snowy Escape pack but I believe it's now a base game feature. You can set the footwear rules by clicking on a shoe rack if you don't have the Snowy Escape pack with it's little "Taming of the Shoe" footwear sign. It will offer you some options to choose from like removing shoes and wearing slippers. All Sims will follow the rule you set. With winter clothing I usually have some indoor winter clothing chosen for my Sims so I can change them into a sweater or cardigan instead of an outdoor coat once indoors. Usually the first couple of outfits in the 5 allowed will have outerwear and the rest will be suitable for indoors, but it requires changing them manually.

Flickering lighting when using glass walls | EA Forums - 12482257

Good afternoon, I’d like to request that these actions be automated. I don’t want to have to click on the door myself every time I see Sims having sex.

I know about the shoes, but it doesn’t look realistic, and Sims don’t hang their clothes on a hanger or put their shoes on a shelf.

As for the girl’s issue, her light flickers rarely. Mine just does it all the time. This is a problem with hexagonal rooms that have a platform, transparent walls, and a transparent roof.

You are not going to get clothing change automated, unless you use mods. If you are on PC, there is a "no outdoor clothing inside" mod that I used to use. I don't know if it is up to date, but you can google for it. I no longer use it and change clothing manually because one button click isn't that difficult. The only mods I use now are to basically fix bugs that EA have not addressed fast enough for me. As for the unrealistic way for shoes and clothing to be changed, it is just how Sims 4 does it.

Manually clicking the door and locking it for everyone but the parents just means your child sims can't access that room to witness woohoo. That is all you asked was for a solution. I know you may hate manually doing things as per your previous responses, but the option is available that fixes your problem. I even lock doors to rooms so for example only the parents can use the master bathroom.

As for the bug you mentioned, it is in the bug forum. Bug or glitches can effect players differently, depending on indiviual computer specs or console type. Adding to the post in the bug forum may help fix your issue get addressed faster. 

2- That would require lots of animation and the team is not a fan of making them. But i understand what you're saying about the shoes, i'd actually like t see sims, at least, have a "touching the foot" animation and then the shoes disappear, something like what they use on GTA V RP. For the jacket issue maybe that's happening because of the cold temperature, that can kill sims.

3- Well you can lock the door, but as you said you don't want to be doing it everytime, the easiest thing to do is let the door locked for everyone but the couple. And if there's something there that the whole family needs you should place it somewhere.

4- Yeah, i agree. I even made a topic suggesting something less intrusive a while ago (is it similar to what we have in paralives??):

Could you add the ability to load a neighboring lot by clicking on it without a loading screen? There’s even a mod for this already—it’s time for the developers to implement it too. We’d be very grateful. 

There's a mod for it in relation to Residential Rentals. But even then the mod only allows you to load into the other unit with your current household. The engine itself requires a hard reload of the lots when you are switching to a different household. This is because of the data that each household stores and when changing to another household the game has to load all of the data.
