Are reading list and tasklist the same terms?
No, they are not. While tasklist is a form of to-do list sorted for priority, which is determined by the Value/Time ratio, reading list is the most important form of a tasklist, in which each task is an article to read. Furthermore, in reading lists the Time field is filled out by SuperMemo and reflects the length of the imported article, while in tasklists you have to determine it yourself.
