For example, when you want to make a note while web browsing or making phone calls, you simply swipe down the status bar and launch Simpleaf.
You can also make a note, at the same time you are looking at the screen by making Simpleaf translucent.
Notes can be transmitted to mail-apps or Evernote and so on.
