Yop I use this plugin since January 2019 on a Waterfall network.
I never had a problem using the plugin, so very good work.

Works from version 1.16 to 1.18 without worries, I also specify that I have servers in 1.14, 1.15, 1.16, 1.17, and 1.18 connected to the Waterfall networks, I have never had a problem to display the results of the commands from these server versions (PaperMC)

If the developer accepts the potential request for improvement would be cool:

Allow to have a permission for each order rather than a global general permission.

Add the possibility in the commands listing the IPs (in addition to other info) to be able to hide the ips if you do not have a defined permission to do so.

Finally allow to translate the text of the results of the commands and the help of the plugin display in the chat (I manage a French community and the level of English of my staff just like mine is not at the top ;) )

I Have been using it on my network and didn't found any problem, thanks for the plugin!

Uhmm, Srry for the bad review :P, I like your work so hard. Only do i need to put this plugin at mijn proxy bungeecord server? <3
