I am not very happy with these additions. So I would like to ask you to tell me which file is responsible for generating the curriculum in the course editor.

I want to add new fields to the existing program settings. For example, so that in the course editor, when creating a curriculum, the section has an additional setting that allows you to create a special offline section. And when adding lessons to this section, the lessons are not created but are displayed simply as text that would be displayed in the program. I would do it myself, I am interested in this, but I do not understand how to quickly find required code file
