[Feature] Weekly view widget and default view option

[Friedjof]

Hi, first of all, thank you for this great app - its simplicity and functionality make it very useful in everyday life.

There are two features that could significantly improve the user experience:

1. Weekly view widget: At the moment, the weekly overview is only available inside the app. A home screen widget showing the weekly view would be very helpful for quickly checking upcoming events, schedules, or timetables at a glance.

2. Default view setting: It would be useful to have an option to select the default view (day, week, month, etc.) that opens when launching the app.

These additions would make the app more flexible and convenient, especially for users who plan their time on a weekly basis.

Thanks for considering this!
