It would be great to have a feature where you could publish an article in Help Center, but hidden, so only a direct link works to access it.
The only way to show an article to a specific group of users is to use user segments. But this is not an option for us, because we`re in a fast moving market with different users each day. It would be helpful to get this feature, so that nobody have to use user segments specific for this 'issue'.
