I’m with twangus on this one. Actually, I just thought about this topic, as with all great thoughts, while in the bathroom.
The forecast is meant for things that are due primarily - it’s your “heads up, time to panic!” (and/or “Let’s plan ahead so you don’t need to!”
Let’s say I deferred “get married” til I was 18. That doesn’t mean that I need to get married on my 18th birthday, merely that I am now able to. Thus, it shouldn’t be on forecast.
If it is something that is important to get done on THAT specific day, then set a due date. That’s what due dates are for, are they not? If only one part needs to be done on that day, then it sounds like a project; treat it as such, and make the one action due and the others merely deferred.
I’m not quite sure yet how flags work with deferments (still a novice, one day in :P). But you might be able to flag it as you initially enter it so that it will show up more prominently in your available items after its defer date.
Bottom line: if it’s important to do that day, than make it due that day. If it’s not, then there’s no reason it needs special attention. Rather, you’ll want to first focus on things due that day (or the coming days) - i.e., the forecast view.
When those are done, then you can look at available actions that had no firm due date and choose from there. This now includes the item that was deferred, so it’s an option. If you won’t see it in the list, then perhaps you need to trim down how many free-floating actions you have (put some projects on hold, etc.)?
That being said, to each his own. I’m still figuring out my own little path as well, so take my two cents for whatever they can be helpful with :).
