The Calendar view needs significant improvement. One limitation that keeps discouraging me from using it is the inability to choose a custom display column for tasks shown in the calendar.
At the moment, the Calendar view always uses the table’s default Display column. However, different views often require different task information—for example, the Calendar or Timeline view may need to show a different label than the main table.
Ideally, the Calendar view settings would include a dropdown that lets users select which display column to use for that specific calendar.
