A chapter's pre-check used to take over the whole window, so it felt like a separate application. It now sits in the chapter page as the first tab, before Chapter, Practice and Sources, with the sidebar and the "Back to roadmap" line still in place.
- Until you finish the pre-check, the other tabs stay visible but locked, with a
line that tells you why.
- Your result stays on the Pre-check tab: your score, the difficulty it set and what
it changed. "Build the chapter" takes you straight to the Chapter tab.
- Each answer's letter now sits before the answer, where you read it first. The
letter keys still choose answers.
- When your chapter's lesson is written, its flashcards and quiz are written
alongside it, so Practice is usually ready by the time you open it.
