Basically have the ability to show / hide content on a page depending on ones group.
Ex: I have 3 groups, I create a 'HOME' page and I want this page to be seen by all 3 groups, but I want each group to only see it's own content, let me know if this doesn't make sense.
Further Example: For a Twitch channel, you have Viewers, Moderators, Editors, you create these groups in Wiki.js and then create a Commands page, I want to be able to show commands for each group on the same page, but one group cannot see the other groups commands.
Hope that clears things up.
