BACKGROUND
This is about the Forecast perspective, and the use of both a Forecast tag, and Planned Date (that displays in Today), and how I use Planned times to create a kind of priority list—somewhat unusual.
I just started seriously implementing: “Today includes: Items tagged: forecast”
I also recently started using Planned dates so items would display in Today—but didn’t like having to manually drag items that didn’t get done forward to a later date—although doing so has the benefit of possibly having to look at / consider if such items should actually be moved to tomorrow, for example, or moved to an even further date, or have their Planned Date removed.
It’s a classic conundrum (for me) of GTD principles (stay aware of your lists and actions, and make decisions based on your current environment), vs. ‘less effort’ (auto forwarding).
BEHAVIOR
With an item set with a Planned Date of today, and with a Forecast tag set to show in Today, when I drag an item forward to tomorrow, the Planned Date is moved forward, and (after cleanup) the item displays on that future date, even though it has a Forecast Tag (and behavior set to show in Today). This behavior (actually) works well for me.
Most people would probably use a Forecast tag or a Planned Date, but not both, for items, but I’ve been experimenting with Planned Dates with a time value I set, and items sort by their Planned time, to create a kind of priority list (I also set Planned times for when I need and/or can only do, something). I.e., I might set “pour concrete” to a planned time of 9am, “buy widgets” to 11am when the widget store is open, and “clean up garage”, which isn’t a high priority, to 4pm.
If I don’t move the Planned Date for items forward, they nonetheless move to the next day (at midnight) based on the forecast tag—which is why I’m experimenting with using a Forecast tag in conjunction with Planned Dates.
I know, the fiddlier you act, the less GTD you get. :)
UPDATE: Now that a day has passed since I started using both Forecast tags and Planned Dates with some items, I noticed that those items with a Planned Date in the past show up in the Past piano key, meaning Planned Date wins out over the Forecast tag, which I had intended to use to cause auto-forwarding of items with a Planned Date to the current date, after midnight.
