By default, when task list pages are requested, AceProject will return incomplete tasks only. However, in the right pane, you can change the default Task Status filter setting from “All Incomplete Statuses” to “All Statuses”.
Furthermore, on project task list pages, you can check the “Remember Filters” checkbox prior to clicking on “Apply Filter”. If you do this, AceProject will remember the way you had configured your filters the next time you bring up the task list for that project.
