Remove Duplicate Lines
De-duplicate a pasted list, line by line — keeps the first occurrence of each line, with optional case-insensitive and whitespace-insensitive matching.
The line that's kept is always written out exactly as you typed it — these two options only affect which lines count as duplicates, never what text appears in the result.
