Frequently asked questions
Does it keep the original order?
Yes. The first occurrence of each line stays put and only later duplicates are removed — or switch to A→Z sorting if you want the result alphabetized.
Can it also strip blank lines?
Yes — tick the blank-line option and they vanish too. The live summary shows exactly how many lines were kept and removed.
