Disable live metrics update

Is this a new feature? It makes my Glyphs app run very slowly, I also often don’t want Glyphs app to automatically update those metrics when they have equations in them because I wish to review how the changes I’m making on a parent glyph effects the glyphs that reference it.

I would like to request the option to disable the live metrics updating.

Are you sure this is done directly by Glyphs and not by a plugin? There is a plugin that automatically keeps metrics keys updated, I’m not sure what it’s called. Maybe you have that installed and active?

Ah you’re right, I was checking the wrong menu for the Sync Metrics plugin!
