It would be great to have the font size dropdown a bit more complex but useful. This website provides different font scaling based on different rules: https://type-scale.com
It would be great to have choices for what rule to use, and then font sizes would be displayed based on different rules, starting with a certain value. Once that value changes, the rest of the font sizes changes... based on the selected rule.
We could also have the option to custom select a font size we prefer.
