Global array $arrSettings

Hi,
and thanks for the plugin.
I call the social button with the shortcode.
I was looking how to customize the align setting, because I need it some time on the left and some time in the center.
Looking through the possibilities I see that there is a global array called $arrSettings, but is not possibile to change the value of $arrSettings[‘ssba_align’] because tha value is get inside the function of the shortcode.
Do you know another way to do that?
Moreover I would like to know if it is correct to expose an array with that common name in the scope environment.
thanks for support
