Icon in Leaderboard

In the change for display style in leaderboard, there is the option to show icon. Where the heck does the icon refer to?

what is the trigger for adding an icon?

I guess it is supossed to use the game icons (command buttons and stuff).

I don't think they'd fit I assume itd use the smaller food, gold, lumber and the little number icons.

What little number icons?

And after what, 8 months, does anyone know what this does? I wanna know too.

Maybe I'll mess around with it later, but I doubt it's possible.
