I am interested in the history of (+). I am tracking the "evolution" of this interaction idiom (and others) and the ways in which user mental models have to adapt to such changes.
I think (+) first meant "expand" as opposed to (-) which meant "collapse." In iTunes it means "Add Playlist" and this has been copied (very crudely) in the Sony Reader eBook Library application. In the original iPhone/iPod Touch Safari interface it meant "Add Bookmark" but after the January 2008 upgrade it has been generalized to mean "Add Something." I am not a long-time Mac user so I wonder if (+) has always been part of the Apple lexicon, or if it is new. Also, has anyone on this list seen (or created) different implementations/meanings of (+) in other products?
