Idea for new functionality

I’m trying to build some graphical elements to use them as components to dynamically create glyphs (for example to have a components system to create fi, fl, ffi, ffl, fff, fffi etc etc…) faster and to be able to update more glyphs all together modifying their components.
I’ve tried to give a custom name to my glyph but I can’t find it in the component list.
I would need some working component, what is not exported in final font file but acts as a library.

Thank you.

oups, now it works.
I’ve called the letter f.liga.
Before I’ve tried f_ligatures but i did not see it in the components panel. But maybe it was a refresh problem.
