I agree. I understand walls and such should be tore down and most structures depending on type, size, and weight though. Maybe add a timer for larger objects to be moved or flipped incase it snaps wrong. This happens a lot and can be pretty frustrating depending on how expensive it was to make. Smaller objects like chests, beds, bookcases, smithy, mortar & pestle for example, should be able to be picked up and moved. Some other objects like the forge can be moved with a damage/repair cost.
One thing I would like to see is pillars being able to snap to wall corners. Could be helpful cosmetically and for structure stability. Maybe 9 snap points in a foundation (center, corners, and middle of sides), and the tops of pillars dont stick through ceilings so much. Also please add flip to sloped roofs. Sometimes no matter where we stand we can never get the slope where we want it. Even with the sloped wall in place.
GREAT GAME though! I enjoy playing it.
