Delayed start tasks

Please please allow creation of automatically delayed or 'deferred' tasks.

Why don't you add a starting date field for each task then allow filtering by this field in the "next actions" view!

See, then if i need to see a doctor on a set date then I just put my task with an appointment date set as 'starting' and then forget about it until the day is come. Or, if I need to pay my CC bill not earlier then some date I just create 'pay CC bill' task set to start in the future and don't bother seeing this task until that date. Or buy someone a birthday present when his/her b-date is approaching.
You get the idea!

David Allen mentions this in his GTD as 43 folders approach, or something alike. You just put things you are deferring somewhere and then check every day if there's something ready to be done. But we don't need to keep checking manually, we have a machine to do it for us!
