We’ve just cleared our 2nd community funded project (the first on Moodlegarage) and Gareth Barnard has already released the updated version of his Collapsed Topics Course Format which allows that teacher/admin to specify if the arrow to expand/collapse topics should be on the left or right of the course page. While only a minor edit, it did require a few hours to clean up the code and turn the hack into something that could easily be manipulated once the mod is installed (with no coding required by the end user).
The plugin is available here: https://moodle.org/plugins/pluginversion.php?id=3358
Four funders helped to bring this project to a success (and donate 10% to Moodle.org): two anonymous, myself and Classroom Revolution, LLC a Moodle Partner in North America. Thanks to all for their support of the 2nd successful community funded development project.
We have more projects being scoped currently, more to come but in the meantime submit your own at http://www.moodlegarage.com/submit-a-project/
