This update now adds API support for 'SuperVanish' and 'PremiumVanish'. If your server has either of these plugins installed, it will enable extra features that show additional stats about if the targeted player is vanished or not and the plugin also will set the mod or admin into vanish as well as spectator when the teleport to the targeted player.
If you do not have either plugin installed, then PlayerGUI will detect this and shall disable the extra features and just use the original spectator mode only when teleporting.
If you discover any other issues with the plugin, please do send me a message or leave a post on the forum with your issue and I'll try my best to assist you.
