I took a look into it, but I can not promise if I will be able to implement it in the next time. Because I don't have much free time at the moment. Notices for myself: 1. The plugin would be able to hock into the Essential IUser and find out if the player is hidden/vanished (https://github.com/EssentialsX/Essentials/blob/d75787726c4869bd5bf338d3f3295c5e8dd6b15a/Essentials/src/main/java/com/earth2me/essentials/IUser.java) There is a bool `IUser. isHidden()` 2. The should be "fake" join and leave messages when the player (un-) vanishes. This can be done with the two Events `PostPlayerShowEvent` and `PlayerHideEvent` 3. I need to check if I am able to send to fake messages only to normal players and not players with higher perms, but I don't want to implement permisions for this. I think using the existing permission `essentials.vanish.see` can be reused (https://essinfo.xeya.me/permissions.html) 4. EssentialsX has a Maven Repo (https://essentialsx.net/wiki/Common-Issues.html)
