Is there any indication if this feature is possible or when it will be implemented? I love this plugin but making handwritten fonts are kind of lacking without it
Hello and welcome to the forum.
I am a user like you. Currently you can name glyphs with ligatures (.liga) and alternatives (.alt). See https://help.fontself.com/en/articles/1237307-ligatures
While ligatures are used automatically in a word processor, alternatives have to be called manually. OpenType Font also knows tags like .init or .final for an automatic alternative of a first or last letter of a word. This is unfortunately not yet available in Fontself Maker. But I hope that it will be available soon. Because it is very handy for script and handwriting fonts.
Have a good time, J.
