Make the drop shadow around the button and chat window adjustable from within the widget dashboard. What I noticed is that the box shadow (with the latest widget) is only placed at the bottom and not at the top, so in our case the window at the top now disappears to white and the same for the our button on a green background. I always want the chat and button to stand out a little from the underlying background. Being able to adjust te box shadow position and color will make it work for everyone
