The problem is our source history/import information clutters the list timeline feature. Although you can filter the list, once you move to another file the filters are removed. Unlike the "status" filter options for notes or to-dos that stick when changing from student to student. I would like to submit the idea to have timeline list filters preferences stick from file to file.
