I not so far as I know have been thought to enhance this command.
- Extend multiple edges at once, not just one at a time.
- Allow the user to choose, by option, if the result assemble or maintain the extended separate parts (this can be important because we understand visually how the area has been extended).
- Give the opportunity, where permitted, to extend an area up to a limit, which is a point, a curve, or otherwise.
- If possible, introduce a dynamic preview of the results, a little as with the extrusion command (type handle), more functional.
