Chat Message Notification

Since the most recent update, it seems that the notification dot on the Rainbow icon in the taskbar shows up for both voice calls and chat messages. Also, there used to be a separate text message icon that would show up in the taskbar as notification of new chat messages, but that went away. This is making it very difficult to identify when new instant messages have been received. It would be really great if there was an option to have the notification dot appear only for chat messages and/or the text message icon notification would display in the taskbar when new chat messages are received. Thank you!
