Navigate inside a project with arrows

[Quick-Eyed-Sky]

When you click on an image in a project, you can view the image along with all its settings. It would be cool to navigate inside the project using arrow keys, like in Finder. For example, if I click the most recently added image (top-left), I see the full image, and I should be able to use my keyboard arrows to jump directly to the previous image (e.g., the right arrow) - without having to go back to the grid.
