1) Add a new course setting to choose between "All sections on one page" (default) and "Each section appears on a new page". Course formats can use this setting to decide how to display.
2) When the second is chosen, the standard weeks and topics formats will now show a TOC on the main page (with summaries about what is in each), and each one has a big clear link to a sub-page for that section. On the sub page we just need one area to add resources, activities, and blocks.
3) Make sure the navigation is all correct, and that all sections have good navigation.
3) (optional for 2.2) If AJAX is enabled, then get rid of the "turn editing on/off" functionality, and just have it on all the time. The appropriate buttons appear only when you mouse-over each activity.
Moodlerooms have provided code for a lot of this in folderview (http://thinkingdistance.org/post/6486856003/folderview-course-format), but we'll need to convert from a standalone course format to make it more central.
We also need to look at Gareth's collapsed topics/weeks format which has also tried to address the same problem, and we should include any additional features from there : http://docs.moodle.org/20/en/Collapsed_Topics_course_format
