Diagonally stack / stagger overlapping time events in day view and workweek view
The day view, multi-day view (i.e. custom selection using the mini-calendar) and "work week" in Evolution's calendar has the same usability issue as GNOME Calendar (see gnome-calendar#104): if you create events whose times and durations overlap, Evolution shows the events side-by-side inside a day's column, instead of partially overlapping them to allow the text to flow, like Google Calendar does (whose layout uses less of the scarce horizontal space inside a day's column, and allows fitting much more text).
Here's a comparison between Evolution (left) and Google Calendar (right), with the same day column width:
