Answer: 
In the "Debug" perspective, there is a "Debug" view which shows the threads of the application being debugged:

There's a little menu in the top right corner, with an option "Show Debug Toolbar". Select that, et voilá:

Window -> open perspective -> Debug. There you go.

Also it will normally open by itself when you run the project in debug mode. You do that by clicking F11 or clicking on the bug/insect icon to the left of the run (play) button in the navigation bar you provided screenshot off.
