Facebook grey-bar-type-widget transparency

[papelet]

Hello guys!
Wondering if anyone has figured out how to add transparency to this widget: grey-bar-type Facebook widget that gives you the option to go straight to post, take a pic and check in without opening the app.
I know it has been done with the Pandora widget so just wondering if anyone has put their eyes and skills on improving this useful-to me- widget.

Thanks
