It is totally crapy. It was developed by Adolph Hitler. Free project management tool Redmine (http://redmine.org) is better in many thousandth times, have more useful features and
the multi-project interface is super crap... the ToDo view on the dashboard does not allow for you to see every ToDo across all projects... seriously?
The best project management software out there. It takes care of everything and then some, making managing out clients and jobs easier than ever.
