With essentials list, if a player is on the server vanished and another player logs on (One with no VNP perms), they can see the vanished staff on the list. I'm not sure if they type in /list after this if the vanished player will show again, but it seriously blows vanished staff cover. I was hoping there would be a way to fix this, so staff cover isn't broken?
Someone suggested that we remove player ability to do /list, and told us that there was no way to fix this except to remove. We don't wish to remove /list or VNP, and were hoping there was some sort of fix to this.

Another issue I've come across is that unlike essentials vanish, VNP doesn't tell if a player is vanished when you do /list, you have to do /v list. This creates an issue with staff logging on and unintentionally blowing another staff member's cover, because they don't do /v list, despite being told to check.
I know there is the TagAPI or whatever it's called, that colors a vanished user's name blue, but it doesn't show it under /list I believe.

And the final issue I've come across is players being able to message vanished staff. We have a few players that like to whisper or message staff privately to check if they're on. With essentials vanish this was not a big issue, for the message wouldn't go through. If there is a way to fix this or a command to stop this it'd be nice. If there isn't a way to fix this, it'd be nice if this could be added later on.

This should be resolved by using the essentials hook in the VNP config. If not, reply here and I'll look into it more.
