issues_194
I am using the veloctiy version of MiniMOTD.
Velocity seems to use the number of connections to display the number of players.

As you can see, this is the number of people in the sub-server.
There are three of them, but one OP is invisible.
The number of people displayed on the sub-server is modified by the vanish plugin(SuperVanish).

This is the number of players displayed by Velocity.
Shows the total player count, including invisible players.
It may be because veloctiy uses the number of connections to calculate the number of players.
So I still hope there is a function to modify the number of online players in Veloctiy.

Describe the solution you'd like
Maybe you can add an option in config to display the current number of online players as a PlaceHolder(MiniPlaceholders). <- I think this might be a good idea.

Describe alternatives you've considered
Or do not count the specified permission group.
Or the solution in the issues_194.

Additional context
Thank you for your patience in reading this feature request.
