[Plugin: Shortcodes Ultimate] Box position

First thanks for the plugin, I love it.

Is there a way to customize box/frame position and size on the page, similar to what is possible with a normal image. Otherwise this would be nice future request. Of course it would be possible with .css, but I would like to be able to customize position and size per box.
