What about a reverse ID search, You can put in a name and it will feed out that person's ID? So say, you are in a server. Someone spams up your server there name is: MasterCheif12984, You dont remember the numbers so you type in:
MasterCheif, and all the names of the people with that name in there pop up along with there ID number.
Also, I know how to make custom bans via the /ban command. But with the update, maybe a GUI would be easier. Such as you type in the ID that goes along with the ban, along with the usual time limit, and reason.
If this doesn't make sense I'm sorry lol.
