if i add a glyph into my font menu> Glyph> Add Glyphs… with the method of A + B = C
the created glyph contains A and B on top of each other (seems glyphsapp consider the least sidebearing from each side)
is there a way to tell Glyphsapp: to put A to the left of B in a wider suitable bounding box, with consideration for A left side bearing only and B right side bearing only. and ignore other sides.
I mean you choose which side bearing for such glyph to be choosed/ignored before glyph is created.
the space in between to be the subtraction difference of the inner ignored sidebearings (the inner here is A right sidebearing and B left sidebearing)
this is useful when adding many glyphs that way.
