I wanted a way to make tangent edges really light in illustrations without throwing them out entirely, so I made the attached script which gives all tangent edges their own style so that they end up on their own layer when Layer > From style is set in the export options:



It also hides seam edges, which doesn't affect illustration output since that already ignores seams, but it makes what shows up in the viewport closer to what the illustration export will look like.
