A great extension in RoboFont is Curve EQ. Glyphs has the Fit Curve extension built in under Palettes. This is similar but doesn’t work in quite the same way.
Q: Would it be technically possible to build Curve EQ as a plug-in/python script for Glyphs?
A: yes
Here is the documentation for the plugins: https://github.com/schriftgestalt/GlyphsSDK
And have a look at the repository of mekkablue. He made many plugins already.
Thank you. I guess will have to learn how to write python script or find someone to help me write a script.
I just updated these tutorials, they will get you started with Python in Glyphs:
