The big picture

Where it is

On your phone, open a topic: The big picture is the box under the score. On a computer it sits under the topic's name. The first sentence is in bold; More shows the rest and Show less folds it again.

When it is written

Until the topic has enough lessons, the box says how many it has and how many it needs. Once it does, the summary is written on its own. If a topic has the lessons but no summary yet, tap Write the big picture.

Only lessons count. Notes, quotes and photos are not part of it, and Unsorted has no big picture.

Keep it up to date

When lessons are added to a topic, moved in or out, or deleted, Update with new lessons appears under the summary. Tap it to write it again from what the topic holds now. It reads Updating... while it works.

Merging lessons into a new topic and grouping topics both write a big picture for the result.
