site and category home sections
Use view permissions on site and category home content sections to define who can see the content.
For example a user working with Streaming Services and Production Products would want to see a quick link to the page containing that information (see image on left), whereas a user not working with these areas wouldn't want to see this (see image on right). So here we applied view permissions so the section containing "streaming services and production services" so that 'confluence-streaming-service-users' could see the section, and 'general-confluence-users' couldn't.

Each Site and Category Home is made up of Sections. View Permissions in Refined for Confluence are then added to the sections (navigation highlight, navigation icons, my activity, pages, etc). By clicking the lock button in the top left hand corner of the section (in editor mode) you can configure which user/s or user group can see the content on that section:
...
Go to: Site, Category home that you want to edit, click the pen to open the Layout Editor
...
.
...
Click the lock icon on the section you want to add view permissions to.
...
Add the relevant view permissions based on the user groups in your Confluence user groups, then hit save.
...
If you remove viewing permission for yourself on a section of content, you will see it in the Layout Editor view only.
