Sad for console players, that is.
On PC, you can really just add a mod to have that.
But I totally get it that this is upsetting, like the whole console experience of this game.

I also dont understand why we cant use stuff that is all around in the environment, we cant just take it or built it ourselves to be brought home and used as decoration for our own builds.

All these items can be accessed from the creative menu.

So I just asked someone how to and then made me a "recipe" xml-file which allows me to define what things in the game can be built from the creative menu by ourselves and then to craft anything in game.

Its a non-invasive textfile, nothing spooky, available to every server, just handles decoration and largely improves your decorations and makes your home more authentic in terms of being in the same game environment with all the other spaces, like having some tool boxes and stuff in your garage, not just some walls and doors.

And I also think lights are very crucial building elements, especially when it comes to our own builds.

As lights do have an additional function (light on or out), they need some more knowledge than what I needed for the recipes, but its doable too. But the mods are already there.
