we are using moodle 3.5 with a custom theme and now we are developing a new course format. This new format change considerabely the course page, and with this changes, I've put the course image on the top of the page, behind the course name (like a banner). The problem is that we would like to extend this new course layout to the participants and grades pages (but only for the courses that are using this new format). My question is: is there any way to override a core renderer from the course format? wihtout having to change the system theme and making a "if" to make sure it applyes only with this course format?
Any other suggestions are welcome.
