Having used it now, I'm... confused about this release. It doesn't work for my images — which are mostly screenshots. I can see how this would be useful for a larger, more casual audience though, with mostly vertical photos.

I'm sorry, but to me the app is ruined. Instead of showing a feed of images and grids, I need to tap for every single image, which is insane when it's like 50 images in a day. Especially since you don't seem to buffer enough, so I need to wait for a second before each image appears.
