What does this plugin do?
By default, multi-page forms on Gravity Forms will start the progress bar count as if the first step has been completed. For example, on a five page form the first page would display 20% completed before the form is even started, and the last page would display 100%.
With this plugin the progress bar will display 0% on the first page and 80% on the last page (based on a five page form).
