Test on any device of your choice: Open a course Check the separation between activities is now a single line and not a surrounding border anymore. Check the separation of sections (only when all sections is displayed) is a surrounding border. Check the first time you enter into a course, if all sections is preferred, all sections are expanded. Check you can collapse and expand sections and this is remembered when you enter the course again. Check that if you enter into a section (from course index) that is collapsed, then is shown as expanded in all sections. Check the section with the last module viewed is always expended when you enter the course (also if you collapsed before leaving). Also text infinite scrolling works ok.
