• Review comments, handed to the session as one paste. Right-click a line or a selection, in the editor or on the
  file's side of a diff, and Add Comment to lich Review: the comment waits in the lich Review tool window, where
  a double-click rewords it and the remove button drops it, beside a note about the change as a whole. Send to lich
  pastes them all as one list, each anchored to its file and lines, the way lich's own review panel sends them. Only
  a paste that landed clears them.
