When in Files, you can create a new folder by right-clicking on an empty space in the files window, then selecting New > Folder.
That is, except when there is no "empty space" in your window.
If there's already a long list of files and folders in your current window, the only option left for creating a folder is using the shortcut Ctrl+Shift+N.
Is there a way I can place a "New Folder" button? I'm not the shortcut kind of guy.
