Blocks: Course contents
If the section name is defined, it is used in the course contents. Otherwise, the block automatically extracts a suitable title for every week or topic from the section summary. If you start summary with a heading (H1, H2, H3, etc), it will use such heading text. If your summary starts with a bold text, it will be used as a section title. If the summary consists of several paragraphs, the first one will be used. Technically spoken, the plain text content of the first non-empty HTML DOM node from the section summary is used as the summary title. If no suitable title can be populated, the current course format's default is used.
You can combine this feature with the multi-language filter to generate course contents in the user's language.
The block fits nicely into multipage course layout introduced in Moodle 2.3.
