I was having trouble following the apple way of deleting photos. This helped me easily delete a bunch of files Id imported from OneDrive. The OneDrive support is awesome too. The only thing Id like to see is background downloading, I tried downloading about 3 gigs of images from OneDrive and had to leave the app up the whole time. Lame.
