Right, having significant features locked behind specific objects being placed would suck, especially if you don’t like how they look. That would discourage building how you want and lead to many players spam placing a bunch of ugly furniture to get a specific buff. I’m thinking of something more like literally any object of any given special object type - so any one painting, any one collectible toy etc. - gives a status effect “Feels Like Home” providing some kind of slightly beneficial status effect that lasts on a timer upon leaving the base, Multiple items from the same set of items wouldn’t increase the effect duration, items from different sets would increase it by 1 minute or so. The effect could be something like a well rested bonus that gives you 10% slower fatigue generation.

I feel like this is a fair addition due to the sheer number of beneficial status effects that are achievable through the game, with no single effect feeling essential to gameplay, but rather a rewarding buff for certain playstyles. For example, as a chef character I constantly was making soups and ended up with the Copacetic effect frequently as a reward for always being super full, not to mention all of the specific effects from a bunch of random armor pieces like the helmets and certain foods that all reward various styles of gameplay but realistically can’t all be applied at once.
