Right now, the user can only go to the next step if all errors are gone from the typography screen. I don't really like that since it removes a lot of options from the users. Maybe they have a good reason to do some things the way they do, even if the Applications thinks its not the best way.
There should be an overlay of some kind displayed when the user wants to leave the page with pending errors informing them about that fact, with the possibility to force the way forward or to stay and fix the errors.
