Assembla provides a number of ways to manage tickets. We have added drag and drop sorting to allow you to move tickets between milestones.

The sort view displays. To see all tickets, make sure that all milestones are displayed.

Move tickets between columns by clicking and dragging.

This is really pretty cool....but is not very usable (for me anyway) without an ability to filter the lists.
Drag and drop ticket sort is fantastic feature! As a manager, my most common use of it is rearranging priorities for each user. Could you include filters to show only tasks associated with a particular set of
1. Users
2. Milestones
