As of now, we use a select element to toggle extra accessibility features.
The simplest solution would be to add an option in this select. I’m not sure that’s the one we’ll keep since it doesn’t allow to select this font without the other accessibility changes.
The best solution might be to separate all of those different accessibility options and gather them in a new category in preferences.
I opened a ticket about it
