Maybe it’s just me, but Finder is one of the default Mac apps I find most annoying. Even though Apple introduced tabs to the default experience a few years ago, Finder still makes it harder than it should to move files from one folder on your computer to another.
Commander One, a Finder alternative for OS X 10.9 and above, makes Finder better for power users. It adds the ability to drag and drop files between two folders displayed in side-by-side panes, not windows or tabs. But there’s more to it than just that.
