New media: 'Create a new gallery' button should indicate that it's the first of two steps

When creating a gallery, the primary action button at the bottom of the screen says 'Create a new gallery'. This button is actually the first of two steps, but this button doesn't make that clear.

It should either have an ellipsis appended, which is a standard UI convention for a non-immediate action, or it should say something like 'Next »'
