Currently wrapping up the texts and redoing the screenshots for the Glyphs 2.5 Handbook. Please use this thread to let me know about any mistakes, omissions, typos, inaccuracies you came across, or passages that were hard to understand. Or any other suggestion or request you have.
The Glyphs 2.5 Handbook is not yet available; it is being worked on. The currently available version is the Glyphs 2.3 Handbook available here: https://glyphsapp.com/get-started
Linked URLs and summary are fine, but also very handy would be PDF-bookmarks/“Lesezeichen”, which can be generated writing the PDF from InDesign (see screenshot). This would make the PDF better accessible.
The whole stuff about masters, axis, variable fonts would be a good candidate for more explanation (the tutorial is nice but too simple). Maybe with a real life example.
