Two kinds of flag. A photo gets a BLUR badge when no region of the frame is sharp — missed focus, camera shake. It gets a SOFT badge when the frame itself is fine but the subject's face is not, which a whole-frame score alone would miss. Frame scoring runs passively as thumbnails load; the face check is a separate pass you run with Check focus in the filter bar, since reading every face costs more time than a thumbnail sweep.

Review in one pass. The Blur chip in Browse's filter bar shows every flagged photo, BLUR and SOFT together. A second click switches to whatever you've hidden, and a third returns to the normal view. The Clean chip is the opposite: one click to see only what's left once the flagged and hidden photos are out of the way.

Keep, hide, decide once. On a flagged photo, Keep clears the flag for good — it never flags that photo again. Hide pulls it out of the working view without deleting anything, and Unhide brings it back. In the full-screen cull view the same choice is one key: K to keep, H to hide.

Set the sensitivity in Settings. Under Browse & Preview, pick from four levels: Off keeps scoring in the background without ever showing a flag, Lenient only catches unmistakable blur, Moderate is the recommended default, and Strict catches more but can flag a soft-looking keeper along with it. Changing the level re-checks what's already scored right away — your Keep and Hide calls are never touched by a level change. A separate toggle runs the focus check automatically as each card ingests, at reduced priority so the copy itself never slows down.
