[REQUEST] retrieve done items under a project or category

[bgheneti]

Statement of purpose
I do solemnly swear (or affirm) that this is an API feature request and not a Marvin feature request. For a Marvin feature request I would use Product Board.

Is your feature request related to a problem? Please describe.
In the docs it states

Note: this endpoint previously returned done items but now only returns open items. Please get in touch if you need an endpoint that includes done items.

It would be great if this was supported because I want to be able to track completed tasks in a project or day.

Describe the solution you'd like
A ?done=true query parameter for the children endpoint to get the done tasks
It would be great to also have this for the todayItems endpoint.

Describe alternatives you've considered
I would also consider an endpoint that returns done items within a certain time frame (eg. past week) for a project/category or all projects.

This would be extremely helpful! I would second this.
