Parallax without all options

Hi,

Great and promising plugin.

When I want to use the parallax element, I get the options for adding a base and a floating image and to define direction they move. But I don’t have any options to set the dimensions and offset for the images.

Tried both in Layers theme and in the Aesop Story Theme that is downloadable via github.
