I also think it would be great to have masters that do not cover the whole glyph set. If I want to draw a glyph for an intermediate weight exactly like I think it should look like then there is no way of using that shape for the interpolation of other weights.
As an Example, I would like to draw:
· Extralight complete glyph set
· Extrabold complete glyph set
· Regular only a few glyphs
… and then use the drawn Regular characters for the generation of the Light, Semibold and Bold.
Seems impossible to simulate right now, even with the bracket trick (which doesn’t interpolate after the cut-off).
Seems like a common problem, no?
