Add options for color and greetings?

[gr8bit]

It would be great if we had fields for the primary widget color and the greetings, as in this official HTML-snippet:

<!-- Your Chat Plugin code -->
<div class="fb-customerchat"
  page_id="XYZ"
  theme_color="#009ee1"
    logged_in_greeting="Hi! How can we help you?"
    logged_out_greeting="Hi! How can we help you again?">
</div>

Could these be implemented?

Thank you for the template!!

Edit: It seems I misunderstood the template - I thought it also inserted the div element above but it seems it doesn't.
