This might sound wierd, but I personally think that background disabling option might be helpful too.
I had to delete them for quite a number of times and for different reasons, like too many white/very bright colors, combo colours blending with the background too much (this especially applies to hidden), or, err, general dislike of a background (after all, there are pictures which would irritate you when you're forced to look at them for 30 minutes or something), maybe a mix of those above.
In all the above cases black screen worked just great.
I believe same reasoning as with storyboard disabling might work here too, except backgrounds are mostly random pictures from internet and I think it wouldn't hurt the mapper as much as if I've had to delete the storyboard he took time and effort making.
