Why not have the best of both worlds: Show Best and Source by shift-clicking on the ones you want. You can also turn on Show Invisibles in Source view to get more info:
Perhaps I am a bit slow here but where you talked about shift-clicking item 2 in the response to Ed’s post, when I do that nothing happens. It sounded like you were saying an individual item in the list could be changed back and forth between “Best” and “Source” by shift clicking. I get the contextual menu when I control-click item 2 which is shown below.
I don’t see anything in the contextual menu to make items change in the part of the window shown in the your image. What am I missing here?
I’m sorry, I was not clear. Shift click on Best & Source:
Individual list items cannot be shifted from best to source within an explorer. You could double-click to summon a viewer window for a particular value and then move between source and best there.
