  - Highlighting
-     - When you highlight text in the input or output, the offset and length values will be displayed and, if possible, the corresponding data will be highlighted in the output or input respectively (example: [highlight the word 'question' in the input to see where it appears in the output][8]).

  - Save to file and load from file
      - You can save the output to a file at any time or load a file by dragging and dropping it into the input field (note that files larger than about 500kb may cause your browser to hang or even crash due to the way that browsers handle large amounts of textual data).
