I go back and forth on this one. On one hand, it does not really add anything and for a long time I did not really use it. There isn't much point without an appearance system (or a more crucial one). ...
First, I don't feel we have enough clutter, especially single slot clutter, and I do like to use it in builds. But I also dislike playing in overly cluttered houses were sims can't get to certain things because of it.
