Line Tools
Clean up any list of lines: dedupe, sort, shuffle, number, trim, remove empties, and add prefixes or suffixes. Every operation applies to the current result, so you can chain them, and undo steps back one operation at a time.
Tips: operations transform the text in the box directly, so chain them in any order (for example: trim, then remove empty lines, then dedupe, then sort). Undo steps back through up to 50 operations; your own typing is also snapshotted, so undo will not eat manual edits. Sort numeric reads the first number found on each line, keeping non-numeric lines at the end. Number lines prepends "1. ", "2. ", and so on.
