Stoping anchor propagation

Is there a way in Glyphs 2 to say don’t propagate anchors in this glyph?

I have glyph, say Aacute that has A and acute components, but I decompose this glyph in ccmp feature so it will never be used in in mark positioning and I don’t want anchor to be propagated to this glyph.

I have quite a few number of these and trying to see how much size saving I can get in a variable font but not adding these glyphs to mark positioning lookups.

I don’t think there is a way to control this. I’ll see what I can do. But you could leave those glyphs empty if you never see them. That would also avoid the extra mark feature.

That is what I usually do, but this time I wanted to keep the placeholder glyphs as fallback for environments without OT support.

I added a Propagate Anchors parameter. It will disable all anchor propagation. You need to check if that breaks anything.

Is this a boolean or a list of glyph names? A boolean is too coarse for this project, but it will be useful for other projects.

It is a book for now. But I figured that it needs more control.
