First of all, thanks for the awesome add-on. It is currently the best speed dial add-on for Firefox as far as I know.
But personally it would be better if I could customise the new tab page a little more, e.g. stacking the dials to the left. Such requirements can hardly be categorised and supported all by the add-on itself, so what about simple allowing custom CSS styles to be applied in the page? FWIW Speed Dial 2 has this functionality in Chrome (it's still quite broken in Firefox though).
