I need an app to manage the various projects that I have going on. In some ways, you can think of it as a todo application which has subtasks, projects/groups, action lists, sorting via time till due/time taken/project/importance etc.
If you have the time, check out this site where there guy goes through a number of options and criteria for a good GTD (getting things done) application.
For starters, Astrid cannot sort by tag/project and non have sub-tasks.
I'm really hoping there is a project management app out there and someone can help me.
