Currently it is difficult to clearly see multiple events in the same day.
While you can change the 2nd event category color - that changes the color of the FONT, not the BACKGROUND.
With all day events, the BACKGROUND of the event title changes, not the font - which makes it stand out MUCH MORE. Would be great to have that option or have that be the default so that two or three events in one day are clear to see when viewing the calendar.
Yes, there is a dotted line separator between multiple events right now, but it is not working well enough to separate the events.
