I think that the tokens should have a "Quick reference" field that can be viewed when you put the mouse over the token. I put an example in the attachment, with the mouse over the blonde girl.
Also, perhaps certain syntax could be used in the field to have it auto-update things. Like {BAR1} showing the values in Bar 1 and updating itself. I think there should also be a symbol that allows for quick editing of the quick reference field.
