I'm looking for a photo viewer that allows you to view images Full Screen and navigate using easing keyboard shortcuts or gestures. I'm looking for a photo viewer that does not create folders that are not useful and does not sort them itself, but instead uses the folder structure that I have created in Finder. I used to use ACDSee on Windows, but I hear the Mac version is not much good. Xee has terrible keyboard shortcuts and gestures, and Sequential is very buggy. Any ideas?
