Alignment Zones

Hello, I wonder what this window is doing … what is Position and what’s Size? Thank you!
Best,
Morten

Alignment zones help create an even vertical alignment at low
resolutions through overshoot suppression.

Position is the relative location (y-value) and size is the size of the zone (positive goes up from the “position”, negative goes down from the “position”)

That’s the gist of it, read more about it on pages 19 & 87 of the Handbook: https://glyphsapp.com/content/1-get-started/2-manuals/1-handbook-glyphs-2-0/Glyphs-Handbook-2.3.pdf

Thanks so much!
