A small everyday UI feature:
Having the ability to add small formulas in the same way as metric keys for strokes.
Current behavior is that you have to type in both manually. Meaning that if you want to update one, you need to update the other one accordingly. Since Glyphs already has a language for it, it would be great to have it here too.
- Same W as H (keep things mono linear)
(would be the same behavior as the current way to do it, but in a more explicit way)
- H is x0.75 of W (keeps the same ratio of contrast)
