I noticed new behaviour of editing values in the info box, and I am not sure if this is intentional or some kind of bug:
when using the tab key to iterate over the values in the info box, there have been two »circles« in Glyphs2:
Metrics
LSB>RSB>width>LSB>RSB>width>…
Kerning
LeftValue>RightValue>LeftGroup>RightGroup>LeftValue>…
see screencast: https://recordit.co/wdpMceMZxI
in Glyhs3 kerning and metrics values are not seperated, and iterating over these values is not cycling, instead it jumps to pointsize value and after that it disappears, as you can see here (version 3033, MacOS 10.14): https://recordit.co/e2OStS1aLm
If possible I would prefer to have the »old« behaviour in Glyphs 3.
