aCalendar+ has the best week view concept that I've seen. It arrays the days in a grid of 8 boxes, the last one being a miniature month view, in either a landscape or portrait view, and it only lists appointments, not every time slot of every day. Proton Calendar only has a portrait view with 7 extremely thin columns, which can be very tedious.

Proton needs some more options in this area! The 3-day view is better, but it only lets you see a couple of days ahead, not getting the picture for the full week in one glance.
