Design view or the Form Designer lets you re-arrange the location of the fields on the screen. Design view is used exclusively for the Detail View
and Edit View
To design a view for a table, go to the table and view you want to change, then go to Design > Form Designer. Your page will reload with a dotted background. Click and hold the the field you want to move until a multi-directional arrow appears, then drag and drop it in its new location.
You can also move the "Save/Copy/Cancel" buttons that appear at the bottom of a page.
