Many applications have a lot of content on each form. If this is the case there needs to be some way to separate certain sections. To achieve this separation Microsoft (and therefore most developers) uses separating lines, but this UI is not perfect because:
We recommend using bold instead of dividing lines because:
❌ Figure: Bad Example - This is the Tools - Options from Internet Explorer and it groups each section in a groupbox - busy UI.
❌ Figure: Bad Example - This is the Tools - Options from Outlook and it uses dividing lines for each section.
❌ Figure: Bad Example - This is an old screen from Code Auditor - the dividing lines are not required.
✅ Figure: Good Example - This is the new screen from Code Auditor - the bold title and indenting are the best way to show the sections.
