In the preview window, it would be nice to shape combining marks based on anchors, the way it works when you process a font with AFDKO or Glyphs.
AFDKO uses the Glyphs convention for anchor names when placing combining marks:
The base anchor — the point where a combining mark will be placed — is a bare word like "top" or "bottom".
The mark anchor — the corresponding point in the mark glyph that will be placed on the base anchor — is that same word, preceded by an underscore, so something like "_top" or "_bottom".
For example, even if there is no U+0227 LATIN SMALL LETTER A WITH DOT ABOVE glyph, U+0061 LATIN SMALL LETTER A followed by a U+0307 COMBINING DOT ABOVE should match the top and _top anchors and shape it, like it would if you ran it through AFDKO.
