Please see my suggestion (described above) implemented in the image below.
The legacy method's button (with the very familiar download icon) has been
retained with a different tool-tip message, and clicking on the button has a
different effect - switches to the grid view. If this button is retained for 1
or 2 releases, it will help existing users to discover and transition to the
new ui-grid menu.
