Getting Things Done - Thinking Rock

Some months ago, I read the book "Getting Things Done" from David Allen.
There is also a Software application build on the Netbeans Platform.
The Application is called "Thinking Rock"

A short description can be found on Wikipedia.

I'm using this application to collect my things, but I was missing to see
actions, which should happen some days in the future. I saw only
the actions for the current day.

When you view the Actions, there is a toolbar with a filter.
You can edit the filter.
Select the "Action date <= " and set the value to e.g "One week".
so you see all actions one week before the occur.
