With today's updates, Canonical made some changes to the upcoming Ubuntu 12.10 (Quantal Quetzal) operating system, regarding the GNOME packages, especially Nautilus.
After revamping the Session Indicator last week and the ability to sort time zones in the Date and Time Indicator, the Ubuntu developers updated the GNOME packages in the upcoming Ubuntu 12.10 operating system to version 3.5.4, which we'll announce later this week.
More exactly, the GNOME 3.5.4 development release comes with a revamped Nautilus, which is now available in the daily build version of Ubuntu 12.10.
As you can see from the screenshot above, the revamped Nautilus comes with a completely remodeled toolbar layout, new sidebar icons, new search function, and the app menu was moved into a button on the toolbar.
It also comes with features like Copy To and Move To actions, notification when ejecting volumes, various tweaks to the list view, and lots of other small improvements and fixes.
