5-star material (w/ minor misses)

best pf its kind + super-helpful

it just works for image-triage. full stop.

its perfection lies in simplicity. - still some things would make it more professional & effective; like: undo, sort into multiple albums, apply sorting to individual albums in same manner, etc.
BUT overall: effective, non-replacable
