立刻加载所有的资源通常没有意义，你只想主菜单出现在屏幕上，然后按照他们需要的去动态加载其他的模块。
It often doesn't make sense to load everything at once. You want the main menu and screen to appear, and then load other modules dynamically as they are needed.
UbuntuOne不再出现在应用程序主菜单中（现在被安排在位置菜单下，而不是以前的附件次级菜单中），而且在Rhythmbox中也可以访问——因为现在这个软件中集成了音乐商店，就像iTunes里一样。
Ubuntu One is not on the main menu anymore (it’s now under Places instead of Accessories), but you can also access it through Rhythmbox - because now you have a music store built in, a la iTunes.
还要注意主菜单已经展开了——并且出现了两个新的菜单项：Source 和 Refactor。
Also notice that the main menu has expanded to include two new menu items: Source and Refactor.
