Good morning.
It has recently struck me that messages can pass me by in chat, it's difficult to keep track on everything that's going on, and especially then if something is directed at you in the flow of nation chat f.x.
My suggestion therefore is:
If anyone includes your player name, either by just typing it or if they choose the reply option, the message for the player with that name will be highlighted in a specific, easy spotted color, like cyan or red, alternatively it could also be bold.
