Idea. Add different sound alerts for different message types: area alerts, personal alerts, group alerts, village alerts, and kingdom alerts, with customizable options (on/off, select alert sound).
Reason. Often, when you're engrossed in something, you don't notice a message has arrived, especially if you have multiple tabs open, and by the time you notice, the person has already left or it's too late. Social aspect is quite important in Haven, and being able to quickly learn about messages and respond will have a positive impact. It's also convenient.
Note. Without customization, it would be annoying.
Different alerts should be added to avoid confusion and to help you identify the message type by the sound and find it faster. Should I resolve this urgently or wait until I'm free?
