Hello
Is it possible to create Swashes and Initial and terminal (beginning and finals) forms and how to assign them?
Thank you

Fontself Maker does not yet support such contextual features, so the only way for now is to use alternate glyphs that you can then manually pick: https://help.fontself.com/making-fonts/alternates
