The most helpful thing is being able to see all of my tasks that I have in one place regardless if they are due or not! Other than this there isn't any really bad things about task merlins system - just how much we love having everything together for ease purposes at work. It's great knowing exactly what needs doing each day because its always right where i need it when i open up excel/word etc!! No more messing around trying figure out which project was next after finishing last nights so many times now :).
