Why a nightly rollover beats a giant backlog
A short daily reset keeps the Today list honest and archives what you actually finished.
A backlog that never resets becomes a graveyard. You stop trusting it, you stop opening it, and eventually you start a new list somewhere else.
A nightly rollover fixes this with almost no ceremony: at a set hour, everything you marked done or irrelevant moves to history, and the Today list empties so you can rebuild it fresh in the morning. The categories stay put. The work you actually finished is still searchable.
Pick a rollover hour you'll actually be asleep for
4am is a safe default. If you're a night owl, push it to 5 or 6 — the point is that the day flips over once, cleanly, without you having to think about it.
