In the top right corner?
I just opened up this font created in Glyphs 3 into Glyphs 4.

G4: Note icon for each and every glyph?

It’s a low importance question but why this small note/document icon is showing up for each and every letter in a font that was initially created in Glyphs 3? I’ve checked Edit-Info for Selection - there is nothing there. [Screenshot 2026-08-03 at 09.40.40]
