Hello,
I think that the "waiting" state is useful. I have actually been
wondering why none of our competitors (that I know of) has it.
Speaking of re-design, another feature that I've found crucial to me is
the ability of choosing the task ordering. Every morning, I'd like to be
able to quickly sort tasks in the order that I will execute them (in
the workview). Then, during the day, I will just pop the top task, do
it, and repeat. One competitor that has this is Pivotal Tracker
