I have several variations of the font Fira Sans installed, including eg. Fira Sans Hair.
In the Kdenlive Titler, however, I cannot select Fira Sans Hair, there is only the main font Fira Sans, with variations Light, Normal, Demi-Bold, Bold and Black.
In other programs (eg. LibreOffice Impress) I have as main fonts also Fira Sans Four, Fira Sans Eight, Fira Sans Hair, etc.
Is there a way to make the other Fira Sans fonts appear in Kdenlive?
