The month view in proton calendar shows events for each day, which is cool, but it would be cool if I could see when events start each day.

Business Calendar Pro has this option. It compresses the time, so for example for an event starting 12:00, it shows "12 Workout". For an event starting 15:30, it shows "15:30 Meeting".

These fit in the tiny day and they add much more information, because I can easily see if I have morning free for example, when first event is at noon. I don't have to click at events.
