slideshow: show (exif)info

[thire]

When I use the slideshow:
*) is it possible to add some background and not just to have (white) letters, so I can read the fileinfo I choose to see? (BTW: clicking on "further options" lets them, but they are not shown in the box above it)
*) <Exposure Bias> is somehow strange: just let it show +1/3 or -4/3 or +-0, do don't you do any formatting there?
*) the <Focal Length> could also be reduced: not 45.000 but just 45...
*) let me combine the two options "time" and "mouse" as I can use the keyboard as well... to navigate during the slideshow.
*) Something like a mouseclick and a little menu "play", "next", "prev" would be nice. And a way to return from somewhere in a slideshow to Xnview AND THEN BACK to THIS image in the slideshow.
very minor, I know, but I wanted to mention it.
