I’d love to see a little clock icon near the due date for tasks that are “waiting on…” another task so you can know a task is unable to be completed without clicking on it.
Also, for repeating tasks, there should be an option to either remove the associated subtask due dates. Currently, when a task repeats, the subtasks keep their original due date (which looks like a completed tasks somehow marked itself incomplete). If there were an option to either remove subtask due dates for repeating tasks OR to make the subtask due dates update with the parent task (weekly, monthly, etc) from the original due dates, that would be ideal!
