Submitted Forms Folders make it a lot easier to keep your various kinds of forms categorised and organised. If there is a particular tab that you would prefer to display automatically when you view Saved Forms or Submitted Forms, then you can change that personal setting in the Web Portal.
In the Web Portal go to the Profile icon on the top right corner > Preferences.
Select the dropdown, and choose the tab that you'd like to make default from the dropdown list. Then select Submit at the bottom of the page.
