> When you have Screen and Multiply, there is no good reason to use Lighten or Darken. reMarkable uses the darken blend mode very successfully in its monochrome and colour renderings of highlighter strokes. Multiply would make the strokes darker the more you drew (and there is a separate highlighter colour that uses multiply for this effect), but darken gets just one level of darkening however many times you draw over it, which is normally what you want, and achieving that result by any other means would be much, much more effort, especially once you get to overlapping highlighter and non-highlighter strokes of various colours of each.
