Our configure page has about 10 – 15 different areas where you can change settings. It is difficult for me, with over 10 years experience, to find settings. Our development team merged the settings into logical groups; orders, customers, tax, products, and inventory. Here is a screenshot:
Our team also moved the save button to the top and bottom of the page. Right now, there is a save button for each group of settings. Users get confused and ask if they must save each group individually.
