Notification of Party Invitation

[Eyn]

As topic, when we are not in crafting or gathering mode, it is easy to tell the notification, but, what about when we are in crafting or gathering mode? It would be ideal if the invitation words on chat window(s) are of different colour than the ones existed for crafting and gathering. All is of blue-ish purple and grey colour right now. Party invitation during crafting or gathering is easily missed.
