in the future we could implement the direct link to the public profile with linkedin, we only need to study the best solution.
Maybe as a future option being able to disable the button, so only for login inor registering, but not clickable for other users in the profile
You can already do this, there is a parameter called "See links to social network on profile" in Easy Profile options (but this affects all social link not only linkedin)
Maybe something to think about together with the 'unregister' functionality?
This is a hidden feature already present. We need to write documentation on this.
Now if you want "unlink" some social you can create a link with this URL:
Facebook: index.php?option=com_jsn&view=facebook&task=unset
Google plus: index.php?option=com_jsn&view=google&task=unset
Twitter: index.php?option=com_jsn&view=twitter&task=unset
Linkedin: index.php?option=com_jsn&view=linkedin&task=unset
