What makes a "second brain" fail most is not a missing feature — it is the note that is never re-read. From the tray menu (the Capture section), LightNote brings old notes back: Random note opens a random .md note from the workspace (avoiding the ones shown in the last two weeks), and On this day lists the notes whose creation anniversary is today (same day and month, in earlier years). Both actions are also in the window's General → Capture menu.
The creation date comes from the frontmatter created/date field, if present; otherwise from the file date. The feature never writes to your notes — it only opens them. It can be turned off in Settings → Features (“Resurface old notes”).
