Transparent Bag Slots
 

I've noticed when I move the backdrop slider all the way to the left for my bag windows, the black backdrop still remains. It would be nifty for slots that aren't filled to be transparent. If there's already a mod for this then nevermind. :)
Here's a screenshot to show what I mean, I usually open all bags once I login for easier access to my arrow stash.

Hmmm, you could either edit the graphic and remove the background or edit the xml and remove the background. If I get some time I'll play a little.

you would make the background transparent by editing the alpha layer of the dds files containing the pics used as the background. i think there is two different pics. One is the background and one is the goldish fading effect. you make them both transparent on the alpha layer and job is done. to see the image used, find the bag window in UIBuilder and see what pic is used as the image source
