HOUSE EDITING: Angle locks (0/45/90/180)

[marsu4u]

So I thought while editing my tavern I spend alot of time trying to get things in an "exact angle" and it consumes an unfathomable amount of time. So I thought hey what if we had angle locks while rotating furniture similar to game engines & editing software e.g. "hold down shift to lock onto angles" I'm probably doing a terrible job of explaining this but I hope someone can add to it. Basically the ability to rotate things very precisely quickly in increments of 45, 90 & 180 degrees.
