I think that being able to use Number Values also while drawing would be cool. I am thinking about specifying superior, numr and dnom y offsets. Making .case alternatives only by position is not supported everywhere (Affinity expects .case feature having only sub commands, pos commands were ignored), so it’s always safer to make a new glyph for .case alternatives. This is where this would come very handy too! Sorry if it already exists, but I didn’t find a mention of that anywhere and can’t use it intuitively. Intuitively setting y of a component to =superior_y_offset (value set in Master’s number values) didn’t work.
