Ok not wanting to have to mess with css with every theme we have. The private chat is white on white on many of our chats you may want to use black as the default text that will work with most themes. Better yet, at least give us a starting point where to look in css for your code to change the text color for the private chat.
Great chat all around but needs some tweaks.
1. Change the notification sound or offer options on how to change it
2. Take about 4 sec for chats to show
3. Offer a few default text options so Private Chat can be seen.
4. Make the Start Private Chat more Obvious i.e. Click to Start Private Chat next to the box that starts it.
