Thunar, the default Xfce file manager, has reached version 1.6.0, getting a much-requested feature: tabs.
For now, using middle click to open a folder in a new tab doesn't work so you must right click a folder and select "Open in New Tab". You can also open a new tab using the Ctrl + t keyboard shortcut.
Thunar 1.6 also brings side pane fixes, various cleanups for the toolbar and an option to permanently delete files or folders.
Besides tabs, Thunar 1.6 introduces features like file properties for multiple file selections, support for remote mounts and bookmarks, a new shortcuts sidepane and improved transfer dialog, side pane fixes, various cleanups for the toolbar and an option to permanently delete files or folders.
