It's basically an Eisenhower-style system under the hood — the AI maps urgency and importance automatically based on the language you use. Say "urgent" or "ASAP" and it goes to Do Now. Mention a future date and it slots into Soon. Vague stuff like "eventually learn piano" goes to Someday. You can always override it, but the point is to remove that friction so you can just brain dump and get on with it.
Re: PARA — that's actually something I'm looking at for a future update (projects + areas as organizational layers on top of the priority system).
As for 2do import, there's no direct integration right now, but it's an interesting idea.
