File Collager aims at redefining what file managers can do. It's features include multi-level undo/redo, ability to queue and work on files that are not yet there, extremely customizable drag&drop layout that can be saved and loaded on demand, ability to dock external windows and to keep current path synced between panes. Every feature is at least a bit better - size of every directory is shown, file modifications are highlighted, built-in preview for hundreds of file types, console has navigation buttons, misclick prevention in grids, most text is selectable, you can see exactly which files and processes lock a directory, switch panes to admin mode or a different user, and many more.
