UntamedChat Problems and Suggestions

[Xuwznln]

First, I got this error log in the console.

Second, can you make it possible to custom server name?
Third, can you make it possible to read the players' prefix and suffix? You support for perms plugins like powerfulperms, and I have powerfulperms on bungeecord, it should be possible to make it.
Sorry for my bad English.
Thanks!
