Using borders in layers should scale and respect the scale of the view, not the scale of the layer... or at least be a checkbox to let the designer decide. For example, if you have a picture-in-picture that you want to merge into a 2-box where the smaller PIP scales up to the same dimensions as the first box... the border will scale then suddenly snap to the target layered input's border size. This makes a very natural transition look amateurish!
