When you have a couple details in tasks in your calendar view, the tasks look terrible!!!
You can’t see the name of the task which would be the most important thing but you see all these colored squares for custom fields which are useless in this view.
Also, you can’t choose to display start time, by default it is due time.
I think improving this by making it simpler or giving options for what to display would make the calendar view a lot more useful and less cluttered.
