Glyph members panel always empty

When I am editing a composite glyph, I suppose that the glyph members should be accessible through the Glyph Members panels. However It seems to be showing nothing at all times, and I couldn’t find another way to access the members to manage, reorder,..etc.

I am using the FontCreator 15.0 professional version, and in previous versions (13.0 and older if I remember correctly) I could manage the glyph member by double clicking on the member on the canvas.

Am I missing something here?

The Glyph Members Panel is for Colour Glyph Members; not for Composite Glyphs.

I see.

Is there a way to view all Composite glyph members and manage them?

Use the side panel to view all composite glyph members. Right-click, and select Used By to see which composite glyphs use them.
