The documentation states:

default_calendar_view = monthly - Default view of the calendar. Can be monthly or daily. Weekly view is not supported.

Also the roadmap does not mention a 'weekly view'.

For me personally, a weekly view is crucial in a calendar app to plan the...week. So the questions would be:

--> Is a weekly view planned for some coming release? 🙏
--> If not, is discarded due to difficulties in implementation or just not considered yet?
