Mary;
I am using Backdrops and I think it is a great addition. I have two suggestions for future features:
1) Make Backdrops a Screensaver option. I want it to automatically start not just have to use the power button.
2) Make an option to have a caption on the backdrops. This should be a toggle option. I love the artist and photographer content, but I would like to know the title of the painting or the location of the picture.
