When I use Doit.im I am looking at the tasks that needs to be done, in the "today" section.
The Due dates are now placed in the right side of the screen, which means that I cannot see the duedate easily.

Furthermoe the startdate is not important, because, since I am in the "today" section, I know it has started.

If you exchanged the two placements, "Due date", and "Start date", the most important date (Due date) is shown to the left, right NeXT to the task, easy to see.

Easy great improvement :)
