Gallery Plug In Enhancement Request

Requesting an enhancement for the Gallery Plug-In. It would be great to be able to directly control the color of the caption text as well as the background color of the text box. As-is, the linking of the text/background color to the global theme colors has limited the ability to get a very clean look (e.g, white background, black text). Also, would be nice to control caption alignment (center, left, right). Thanks for considering.
