Consider only showing time of event at large window sizes
Current Issue
At small or even medium window sizes, event labels are quickly ellipsized in the month view, which makes it difficult for users to understand what the event is about.
Proposal
Hide the time of the event at small and medium window sizes, and only show it at large sizes. Users can of course still hover over or click on the event, or use the sidebar to see when the event happens. This behaviour is also in line with other calendar apps such as Calendar on macOS.
Alternatives
Instead of the full time, put down the short form of the time. For example, "16:00" can be written as "4p". However, I cannot think of short forms for "16:50" or "09:25"
