🔖 Feature description

Right now, I have two choices for completed recurring tasks:

• 🏁 keep gives me an ever-growing list that makes my tasks file more difficult to manage.
• 🏁 delete gives me no way to see a task's history, or what items I managed to complete for the day.

I would like a third option: 🏁 keep X, where X is an integer.

✔️ Solution

• Day 1: I define a daily recurring task, and include 🏁 keep 1 in the definition..
• Day 1: I mark the task complete. A new task for Day 2 is created, with Day 1 retained underneath.
• Day 2: I mark the Day 2 task complete. A new task for Day 3 is created, with Day 2 retained underneath. The task for Day 1 is deleted.

Because 1 previous item is retained, I can see the completed task in my query view for the day.

Similarly: I can set the task to 🏁 keep 7. Now I can see how consistently I've completed the task during a weekly review.

❓ Alternatives

Archiving tasks on completion to another note file, or a tool for cleaning them up (say, "run this to delete any completed items older than X days"), would help with many of these use cases. I do think this is distinct enough to be useful in its own right, though, even if it's only for seeing your task progress during the day.

Do you have any ideas about how this could be implemented, given that task lines are independent entities?

Because 1 previous item is retained, I can see the completed task in my query view for the day.

A new feature isn't needed for this particular case, though.

I just phrase my daily note to search for any recurring tasks that were created today and have onCompletion is delete...

I'll leave this open a day or so more, in the hope that you have time to reply...
