simplicity recourse management good price

I can manage tasks by category with subtasks to any level. The user interface is intuitive and laid out the way I work. It is easy to create dependencies among tasks. A tasks can have multiple dependencies. The package computes the critical path. I can track costs. Costs are summed at all levels. Tasks can be grouped into sections. Tasks can be converted into milestones and vice-versa. Multiple people can collaboratively work on projects. The impact of workload is shown by person across time. It is easy to move tasks around to different parents and sections.

I love how easy it integrates into Asana but it is very intuitive interface, better than other project management tools.
