Among the visible differences between Beta 2 and Beta 1, the controversial window manage button positions are unchanged, but the order of the buttons now runs "close-minimise-maximise", reversing the order which appeared in the earlier beta version. The installer has been revamped and now uses WebKit to display a slideshow while installing. Ubuntu One has gained the ability to synchronise Firefox bookmarks and mobile contacts and Rythmbox is now supplied with the UbuntuOne Music Store plugin. Other changes include the use of the new Ubuntu logo throughout applications.
