I figured out a quick and dirty solution to right justifying the buttons.
You have to change two lines in simple-share-buttons-adder.php
change
// center if set so
$htmlShareButtons.= ($arrSettings['ssba_align'] == '<center>' ? 'center' : NULL);
to
// center if set so
$htmlShareButtons.= ($arrSettings['ssba_align'] == 'center' ? '<div align="right">' : NULL);
and change
// close center if set
$htmlShareButtons.= ($arrSettings['ssba_align'] == 'center' ? '</div>' : NULL);
$htmlShareButtons.= '</center>';
to
// close center if set
$htmlShareButtons.= ($arrSettings['ssba_align'] == 'center' ? '</div>' : NULL);
$htmlShareButtons.= '</div>';
hopefully the next version will have a right justification option so this change will not be necessary.
sorry that second change should have been from
// close center if set
$htmlShareButtons.= ($arrSettings['ssba_align'] == 'center' ? '</center>' : NULL);
$htmlShareButtons.= '</center>';
to
// close center if set
$htmlShareButtons.= ($arrSettings['ssba_align'] == 'center' ? '</div>' : NULL);
$htmlShareButtons.= '</div>';
