For now you can simply create multiple directories and each directory should have relevant content inside. Every directory has a unique shortcode possibility.
Yes, one check I can implement quickly, that is the cross-check if someone changes URL with some other directory number so only shortcode related hierarchy can be seen.
Later I will work on roles based restriction feature in upcoming versions.
Thank you for this nice suggestion.
@therustyfox please try the latest version and check the security level feature added for you.
Wow! Thanks for the fast response Fahad! I’ve updated and will try it.
