I really like the many user settings IQTELL offers. This is among my favourites:
It is not exactly pure GTD, but I like to have my actions listed roughly in the order I must or can tackle them. So when I put a “3” in the Actions’ Folder Configuration -> Folder Attributes -> Tab Initial Values -> Column Initial Value for Due Date, IQTELL will automatically put a Due Date for new Actions that is three days (so, about half a week) from the day I created the Action. This way it will automatically show up somewhere between tasks I have to do today and those due in the following month.
Of course, a different due date may apply to this task, but as long as I do not have a more specific target date, this avoids that the Action is completely out of the timeline (when Actions are ordered by Due Date).
