Personally I did not like the way the Discord messages came across on the server with all white text, so I decided to add flair to the PrintToChat on line 435 of the most current version (1.7.4) of the mod. Here is what I did:
PrintToChat("<color=#7289da>[DISCORD]</color> " + "<color=#55aaff>" + nickname + "</color>" + ": " + message.content);
Basically what this does is makes the [DISCORD] tag the color of the Discord logo and the nickname the color of the chat default for in game chat. I'd like to propose that this be adopted to the next and continual versions of the mod.
Feel free to use this change by replacing like 435 with the code shown above to have the same effect on your server!
