Not sure if this is soemthing you might consider, but would personally love. I really like the way you have styled the calendar events in the top right to match the iOS app.
I know design is subjective, but my ideal would be how you guys have styled it there, with the functionality in Fantastical (MacOS) where they have the calendar view, and you can scroll through all the, or select a date in the calendar to jump to that date.
If you could take that bit of functionality, and apply your styling to it in Agenda that would be amazing!
