More rectangular partitions please!

[Themarvin]

That's really only useful if there are floors below you.
More half size partitions would be super useful in FC rooms, apartments, and, well, the ground floor.

You can lift small items and create partitions that way as well, the lofts and stages alone should provide which additional flooring you need, more item spaces for anything apartment/housing would be more of a need especially on medium and large.
