WhyLens: Decision Trackerv2.4

What changed

• RetentionIntroduced an optional weekly digest of due items.

Original release notes

Two additions, both about learning from what you already wrote.

• Looking back — after a decision where you weighed several options, note whether another path would have been better. Nothing is scored or judged; the answer is yours, kept with the decision.
• What you've learned — the lessons you write in reviews now collect in one place, and quietly resurface when you start a decision that looks similar.

Also: an optional weekly digest of what is due. Off by default.
