Though I appreciate the interesting solution for iDraw, I’m still not convinced for the case of professional type design. The point is, digital type design is not just like vector illustration. You need to do more node-specific things, across a wide range of glyphs, and with much more precision.
Just one example: nudge two points to the left by 3 units and up 1 unit. For this, the arrow keys on a conventional keyboard are pretty much an ideal tool. You can perhaps solve that on a tablet too, but not in a way that can rival conventional keyboard and mouse input.
Which poses the question, why would one use a ‘good enough’ Glyphs on an iPad when you can have a really good Glyphs on a MacBook? What would be the advantage?
I can see a .glyphs file viewer for the iPad, with the ability to test instances and add annotations, but not a full-fledged font editor.
