Repeating task due dates & assigning one task’s due dates to another task’s scheduled date

1) repeating due dates along with repeating tasks, Eg I have some same tasks before each class that are the same weekly tasks + same due day but reoccurs

1a) repeating tasks + toggle list under a repeating task that displays future repeats (in list view), so I could edit each subtasks individually Eg I need to call someone in 3 weeks but I want to do it within the time block I have for admin, so I’ll add it as a subtask under admin in 3 weeks

2) It would also be cool if due dates could be attached to events or other tasks’ scheduled date, Eg “plan for___” scheduled for 3 days before Mother’s Day (whatever date that is where you live, it attaches to whatever local calendar you’re subscribed to), or on other tasks and acts dependent on the task’s occurrence it happen, because things move, etc (a timeline view would prob be most effective)

Just want to say that I’m so happy to have found an app design that time blocks in a way I’ve always wanted to. Many thanks, especially for life time option
