Earlier quoted context omitted.
I have to admit that I and most programmer types that I know hate that feature but maybe its helpful for those less tech savvy.
Well, count me as a programmer type that enjoys the feature and is having a hard time figuring out what there is to hate about it.
IMO, it is a better way of navigating around. If I'm wanting to go a child of a folder three levels up, I just click the little arrow next to the appropriate parent, then choose the child. As opposed to up-up-up-scroll-click.
Plus, I still have the option of manually editing it, if I so choose (but that takes an extra click).
It took me forever to notice the "search" box, though. That's another really nice feature, once you get used to it.
