This layout comes by default with a channels list, a track map, a movie, a time/distance and a storyboard panel.
In the bottom part, the storyboard, you can doubleclick a lap to show or hide it, once a lap is shown, you can drag it to move the shown slice onto another lap.
The leftmost part shows on top a list of all the channels of the loaded runs, and, on bottom, a track map representation of loaded data.
The main part (dimensions wise) of the layout shows the time/distance panel. By default, hitting the space bar, only this part will result in being shown, hitting the space bar again, the hidden parts will be promptly back.
