The URL contains the form information that you change. As you change the form it changes the URL to match your changes. When you are finished, you can copy the URL and save it anywhere you like. When you come back, use your copied URL and it will populate the form from your previous visit.
There is also a theme changer for your eyes.
You can sort each column by clicking on the column heading. I especially like this feature. The URL is not changed for the sort or the theme.
As I said, this is in beta and changes will be made for metric use soon. Other user friendly changes soon to come.
Thanks and we really would like your feedback. Leave a comment please.
