On a 14'' screen my calendar only shows 2 events max. If there is 3 events for the same day then only one of the 3 is shown and the second line says "2 others" despite the fact that there is plenty of space left in the "day square".

Reducing padding of each event could help showing more events per day.
Also, when on a 14'' the line showing the days of the week also takes a lot of space.
