Fantastic. I was thinking that it might be cool to be able to embed images (photographs/pieces of paper/clues/hints) and collected information within the information box. This would be useful for detective type games. :)

You can already change the window skin in the current version with the plugin parameters, no JavaScript needed, just a window skin file to place in the /system folder
Also you can change the RGB tone (from 0 (min) to 255 (max)) always from plugin parameters
I can think about adding the opacity option in v2.0 🙂
