Task List Filter

[kintoro]

I am needing some direction. I am a recent convert from the Palm world and used Agendus for the last 2 years. I am trying to make a decision on a PIM but am leaning towards using the stock applications and they are meeting my needs for contacts and calendar but the task application is limited. Does anyone know of an application that improves the task management functionality?

I have searched but this seems to be buried amongst task bar management discussions or full PIM applications.
