List Sorter Sidekick

Select lines in any text editor, run List Sorter Sidekick: Organize Selected Lines into Buckets, then drag lines into named buckets. Choose To Markdown to open a new Markdown document containing each bucket as a level-two heading and its lines as a bullet list. The original selection is unchanged.

The organizer starts with two buckets. Use the + Add bucket button to make more, rename headings inline, and drag cards to move or reorder lines. Ctrl/Cmd-click or Shift-click selects multiple items for a bulk move. Undo and Redo restore organization changes, while Search filters visible items without changing their bucket assignments.
