I would like the option to sort my activities by day of the week. This would be useful because I could compare my routine and habits over longer periods of time easily. For example, I recently wanted to know how many weeks in a row I had run 6 miles on Monday. It could also be used to find patterns, for example if I often skip or modify a workout on one day. This feature would be easy enough to implement because the date of the activity is already saved
