In order to improve the user experience of Moodle and remove clutter from the course screen, Moodle Tracker issue MDL- 48947 was created earlier this year. The tracker issue was focused on clearing the course section as too many buttons cluttering up each section.
Section Menu is the answer to overcome the cluttered screen and a prototype is ready to be tested for the same. You can also test out the prototype here: http://prototype.moodle.net/sectionmenu/
The Tracker issue is marked as resolved and is awaiting review before being added to the repository.
You can also test out the prototype section menus and post your reviews about the same in the Moodle forums thread here: https://moodle.org/mod/forum/discuss.php?d=320445
