There are some new options to help you better organize your places and more will be coming down the road as well. While seats are part of the rooms themselves and don't get commands (and examine), there are more functional pieces we can provide that do provide more use.
Shelves let you display items decoratively where installed. You'll find a few different kinds of these available include a bookcase (which will hold more than books).
These have already existed. General purpose storage, helps clean up your clutter. There are a couple sizes and you'll pay more for natural materials of course.
Designed primarily to hold clothing. They're useful because you'll automatically put things in them according to where they are and how big they are. And when you look at it, its easy to see everything at a glance.
Handymen (and women)
Now, all these items need to be installed and uninstalled in order to make use of their benefits. Installing cabinets and bolting things to walls and such is fairly straight forward, but is not without some degree of technical and mechanical complexity. So, there isn't -A- skill that is required, any of the mechanically technical skills will suffice. It'll take some simple tools to do the job of course, the sort of tools that come from a handyman's tool belt.
More items will be picking up this functionality, but they might not be things you can buy in a store. You'll note there are no locks on the the above. We'll get to that too.
