Customizing the Finder browsing toolbar
One of the thing that used to annoy me on the Mac was that when you press "Back" in the Finder, it brings you to the last page you where, not the previous folder. The way I say it might not be obvious but if you browse with the left alias bar, it makes a big difference. Per example, in Macintosh HD, if I click "Documents" and then "Back", it will bring me back to "Macintosh HD" not to my user Home folder. I finally found a workaround to that: you can customize the toolbar. In any folder, you can go "View" and "Customize Toolbar". From there, you can simply drag the button you want to add to the toolbar. There is also a default option that comes installed with the system. The one I really like is the "Path" button. It basically offers the advantage of both way of browsing as you will have both "Back" and "Path". There are many other options to customize the finder toolbar that you can change at the same place.
