The best thing about this software is it's ability to provide you with detailed information regarding your project schedule in real time so as far i'm concerned there isn't anything bad at all but I think its better if they could add some more features like; 1-The option of viewing different types (i mean view)of reports 2 - A way to send emails directly from my computer 3 - Ability to create new projects rather than just copying them over.
It has helped me keep track how much work we are doing per day & also helps us identify where our bottlenecks lie which allows us know what needs improvement before hand instead waiting till things go wrong then correcting after hours or days later when problems arise.
