Mindjoy comes in light and dark, and you can also change the font used for lesson and chat text.
Changing it
Click your name at the bottom of the sidebar and choose Settings. The settings pages are listed down the left: Account, Profile, Security settings, Email preferences, Accessibility, Agent preferences, Integrations, Classroom Sync and Billing.
Open Accessibility. Content font changes the typeface used in chat conversations and lesson pages, which is worth knowing about if you have dyslexic readers in your classes.
