Get rid of the “Save as default” in font styling and just have the font set automatically to the font when it’s adjusted. Just like how when you work in word document, google docs, when you set the font, it stays at that font every time you work. I constantly have to change fonts and reclick the “Save as default” Font, and it’s really annoying because it doesn’t appear in split screen. Why not just get rid of it entirely and save the font once it’s set, as it’s much more intuitive.

In Notability, they have the Font Adjuster appearing at the bottom, so it is even visible in split screen. It also saves the font automatically, so you don’t have to click an extra button.
