Hi,

I follow the GTD methodology. As you might know, actions which can be done right now are tagged with "next action" or so. If you want a task to be doable in the future use this smart search:

1. This is the usual GTD stuff to show next actions for a specific context (something you can do in the web:
(tag:na AND tag:@web)

2. Now the magic, which will show the task only if the due date is set for today or in the past:
OR (tag:@web AND tag:validfrom AND (dueWithin:"1 day of today" OR dueBefore:today))

Combined it is:
(tag:na AND tag:@web) OR (tag:@web AND tag:validfrom AND (dueWithin:"1 day of today" OR dueBefore:today))

I find this useful because the majority of my tasks isn't due on a specific date, but should be done from a certain date on.

Sincerely, Martin
