input output on track view

Hi,
      when I start a new project I like to use the "Accessibility"  option as this gives me the input/output on the track view without using the inspector but what if I already have a project from a 16 track start that doesn't have the input outputs on the track view?
How do I add them (also the fx on a track?).

Thanks

Open the Listbox (a.k.a. drop-down) just to the left of the timeline above the track headers, and you can choose a preset widget view that has what you want at the moment, or create a custom one.
