A further thought on this - which relates to NSScrollview specifically. There 
should be a way to override the system preference programmatically for specific 
views. The reason I was finding this so frustrating is because I have a very 
wide view that I like to skim using the thumb, but that's just one view in my 
app. Other views that have scrollers are reasonably usable as standard, and 
having the scrollbars always visible in those cases is extra clutter that isn't 
usually needed.

I was looking for a way originally to set just the one scroller to not hide its 
scrollers by setting -setAutohidesScrollers:NO but found that was being ignored 
when my trackpad was switched on. If I set that setting, I expect to mean it. 
Or else there should be an additional setting in NSScrollView, 
-setAutohidesScrollersAndThisTimeIReallyMeanIt:NO
