Spell it: a new quiz. You get a chord name and spell its notes; every miss shows the rule. Smarter practice: missed shapes come back sooner, known ones less often. A stricter "Mastered": right and fast after 14 days away, in Name it and Find it. Name it now asks for the shape's notes, low to high. The Notes quiz tracks all 78 spots on the neck. Every answer shows your time and the goal. Save your progress to a file and restore it. Cleaner Home screen and clearer, shorter lessons.
