I think it would be a great addition and would stop buildings and what not from sliding around when you don't want to. You could still break or shatter them but then it could move freely.
What i mean is make a pin like feature where in the editor you have an option to pin the block you are looking at. kind of like besiege there is a pin feature.
I see, there's no feature like this and won't be added to the current game. I did however express ideas of a sequel before, so you can keep it in mind if I ask for requested features :)
