In order to not multiply topics I add here another minor bug found in the 2.2b version.
You can not open OTF and TTF files in Glyphs 2.2b(816) - I solved this by opening the files in a older, not updated version of Glyphs 2.1.1
Sorry, I made a typo. It should be 816 instead 116 and 2.1.1
The problem appers after instaling the cutting edge version of Glyphs 2.2b(816). I thought its maybe something with the settings of El Capitan but I can open the OTF and TTF files in a pre updated version of Glyphs 2.1.1. I have this problem with all fonts – my own and bought fonts. I looked in the default settings of Glyphs 2.2b(816) but they same to be like in Glyphs 2.1.1. I have no clue what could be wrong.
OS X 10.11.1, G2 [816] – Similar issue here. I can view Features in an Adobe Font (Warnock Opticals) but I cannot view Features in an OTF of mine generated by G2 August 3, 2015. There is a red exclamation mark to the left of the Feature drop-down in Text mode. I can view Features in the .glyphs file though. I will send the OTF via email to you.
The red exclamation mark means there is something wrong with the feature code. Hit the compile button in Font Info > Features. It should give you an error message.
