Transitions is an awesome feature in piwik, to let you see which pages visitors have clicked before and after a particular page.
Transitions works for any given Page Title and Page URL.
It would be very useful if Transitions supports seeing "Previous pages" for any Download file, or Outlink. This way one could know which pages a particular file is most downloaded from, or which pages lead to more "outlinks" clicks.
This was requested several times in the forums eg. today in french.
