Desktop applications fit into four categories of posture: sovereign, transient, and daemonic.
桌面应用可以分为3种姿态, 即 独占 、 暂时和后台.
In many cases, users will not even be aware of the existence of the daemonic application.
很多情况下, 用户甚至意识不到后台应用程序的存在.
As you might expect, any discussion of the user interface of daemonic applications is necessarily short.
因为后台应用在后台运行, 因此关于后台应用的用户界面的讨论,其篇幅必然很短.
