New font, duplicate master, but no way to set Axes Coordinates. Looks like the dialog is broken.
Have you added an axis in the font settings?
Ha No, I tried to do it exactly as it works in Glyphs 2.
I find it confusing to see “Axes Coordinates” that can not be edited, when there is no axis. Or that the Add axis is on a different page from Axes Coordinates…
We are working on improving that.
