I have a multiple master font with two axes: weight and optical-size. Before today I had mapped the optical size onto the built-in width axis, but I notice that recent versions look like they allow the “custom” axis so I moved optical size there. Am I jumping the gun? I know this was an incomplete feature before.
So far it all seems to be working, and the names of the layers have updated in the font info and the layers palette (What used to be incorrectly “Condensed Italic” is now properly “Display Italic”.) But those updated layer names don’t appear in the tooltip when I hover over the buttons to change layers in the main Glyphs window.
