first of I wanted to say thanks for the amazing plugin, I love it.
The last thing, which bugs me is, that the buttons are sitting on a different height, which brings a great deal of visual instability with it. Is there a way to fix that by default? That should be possible to fix with some padding-top on the containers, I think.
Furthermore a small bugreport: If a user doesn't enter a value into the width-field on the settings page, non-valid html gets generated: "width:px;"
