How would I put name tags in front of a specific player's name in the chat menu?
I have a fair amount of experience with lua, but I seem to always mess this up in some way. Could anyone help me out or at least point me in the right direction? Like, which sections of specific modules I have to edit or whatever.

Try cloning the Chat scripts and experiment with them.
In ClientChatModules > MessageCreatorModules > DefaultChatMessage, on line 22 the code says "local formatUseName = string.format("[%s]:", fromSpeaker)". You can change this, which will be the display name. You can add if statements, etc. However, these tags match the player's name, and I don't know how to work around it. You might have to create the text frame for this.
