Touching back on the discussion in #348 and related to the implementation of habits #359 it would be nice to have the option for repeated events (repeaters and habits) not to be taken down from the agenda view.

The use case of this is if you want to see what you did today/last week/last month/last year. Currently, as it is in Emacs once the repeated item is done it's taken out of the Agenda view like so:

Once done:

Looking at your day you would say you did nothing and maybe wonder why you did nothing all day 😄

Also if you want to see how many of the repetitions of an event (say music class) you missed the past month and when you cannot do it in the Agenda now - you have to look at all the repeats for the event.

On the side of habits - say you wanna do some exercise at least every 4 days and at most every 2 days, it would be nice to be able to see all the times you did the exercise in the Agenda view as kind of a tracking thing.

I understand that the current behavior is useful for not crowding the Agenda with many small repeaters/habits, but it would be nice to have an option for them to be there.

Read related issues #348 and #359 first, then trace the agenda view's handling of completed repeaters and habits. Define how an opt-in setting should retain completed occurrences without crowding the default view, and verify behavior for repeaters, missed repetitions, and habits.
