This is nothing Fancy I just had issues knowing someone joined the Support chat because I often listen to music as I am a Web Designer and Developer and I use this chat for consulting possible clients. All I did was insert a Javascript Alert box that says "New Visitor" so that my browser will jump to that tab or if i am on another program highlight in the taskbar.
all you need to do is add
alert('New Visitor!');
to the file: users.js
To find it easier search for "{$s(ht+'/sounds/new_user.wav');" without the " marks.
place it after the ; in the term above.
Please know I am using Version: 1.6.0 alpha 1
Here is the File if you want it. Just change the extension to .js
