(that is I am saying about blogs that don't have auto-save function) Everything may happen, and make you lose what you have just done within some seconds or just a click.
(一些博客不具备自动保存功能)一切皆有可能，就在几秒钟之间，或者一个点击。

Finally, in long-lasting editing sessions, users will be very grateful if you implement auto-save (as illustrated in Figure 4).
