Disable all Social Marketing CSS

I want to implement social marketing on one of my websites and like the idea behind the plug-in very much but I would like to see a way of disabling ALL css used by the plugin.

If I check the box to not load it's css, my ad still shows up in a yellow box.

Off course I can go inside the code to comment the part where the css is loaded but that's not a clean solution.

In my opinion it would be much nicer if in the color dropdown you could choose "None" next to Yellow, Red, Grey and so on...

Is this somehow possible to update the plugin this way?
