The Atlas window
Atlas is three panels: the sidebar, the grid, and the info panel. Once you know what each one is for, you can find anything. Here is the whole window.
The sidebar
Everything you navigate to lives here. Your library sits at the top, then All, the All Tags view, and Trash, your pinned folders under Quick Access, your collections under Smart Folders, and the Folders tree for every project you have added. The bottom row holds the Filter box, the theme switcher, and settings.
The grid
The center is your files. The bar across the top has back and forward, the search box, and the Sort & organize button. A slider at the bottom of the grid sets how big the thumbnails are.
The info panel
Click any file and the right panel fills in: a big preview, where the file lives, its Tags and rating, the prompt it was made with, and its size and dimensions under Properties. Select several files and it sums them up instead: how many, their total size, and the file types.
Pick a theme
Atlas comes with ten looks, light and dark, from the warm default to the pink Berry theme. Switch from the theme button at the bottom of the sidebar, or in Settings under Appearance.
