Calendar: Upcoming agenda view option
The current app only shows a calendar on top and a list for each day you select on the bottom. It's very difficult to summarize and see all of your upcoming appointments, because you have to go through each day to see them. There should be a way to switch away from this calendar view to just see a large list of all upcoming appointments or entries and what date they are upcoming as. There should be a configuration option about which view you'd like the app to default to, whether it's summarized multi day agenda or the calendar/day list mode.
This would be extremely useful. The app on Andriod is disappointing to say the least. You have to click each day to see. Very antiquated and all other mail apps I've used have such a basic function, sad that Protonmail currently doesn't.
