How to customize the Filter > Shape Order window?

Hi there,

I have an idea about customizing the Shape Order window in Filter.

For example, changing the color, adding the shape index at the rightmost bar, pinning the window to make it always on top, which can make me check the font compability more easily.

I’ve found that the source code of Shape Order is at /Applications/Glyphs 3.app/Contents/PlugIns/ElementOrder.glyphsFilter, however, there is no *.py, *.m or *.h file in the folder. [^1]

Is it encrypted or compiled? Can I edit it? Or maybe I miss some dictionary?

Thank you.

This is not the source code but the compiled plugin bundle.

Perhaps other methods like Correct Path Direction or the Compatibility View can help with some of your needs.
