Foundation pieces always have gaps between them, and walls extend out from them. The ability to put walls on foundations, and pillars on corners or sides of foundations/ceilings.
This is especially obnoxious when it comes to wedges which depending on the way they face affect the way pillars stand, which for someone as OCD as me can be quite annoying. Arrows on all building blocks so it’s easier to tell which way they’re facing. Some of these things are covered in mods, but you can’t use those on live servers so I’d really like it if a few things could be changed about placement.
