@alcinnz also, that option doesn’t otherwise change the behavior of gestures. the example raskin uses is the configurable toolbars of some 1990s versions of MS Word. convenient if you’re a power user, but now you can’t document those shared installations (households, libraries, schools) of msword for novices because the toolbars could contain literally anything.
@alcinnz after reading raskin’s book I became hardline against configuration: especially since it would be a topic of argument whenevee apple would change something in OSX (just add a configuration switch!). and so, upon approaching a stranger’s macbook you now have no idea which way the scroll gesture will scroll.
however I’ve softened now that I’ve realised some configuratoon options are essential for accessibility.
