Additional Fields in Single Image Footer

I love the look of the masonry gallery, but without the option to include title and description (or any html whatsoever) in the single image footer, it is of very limited usefulness.
I was able to get the title and description (including html) to show up in the thumbnail caption, however it both broke the single image UI, and is the opposite of where I actually need that information to appear.
Is there any plan on adding the option of additional footer fields, or is there any workaround to add html?
