Simple feedback: Use relative time whenever its appropriate
Longer: What is particularly useful about date ranges is the due date, and its really useful to know when something is due ‘Today’, but its not useful for looking ahead. Currently one of my tasks is due tomorrow, but unless I actively connect the dots of ‘Mar 6th’ and ‘Mar 7th’ I’m going to come in tomorrow and see that I have a task due. Similarly, it would be useful to replace ‘Mar 5th’ with yesterday. Other ways of looking ahead could be useful, but ‘Tomorrow’ would be a great start if I had to see one thing implemented.
