Be one with your sidebar! Apple added this new feature to the Finder to store not only mounted volumes, but also files, folders, or anything else you want to put there. The default set includes your Desktop, Home folder, Applications, Documents, Movies, Music, and Pictures, but it's completely customizable. Just click and drag an item to the sidebar and bam! Quick access is one click away. To remove an item, just click and drag it outside of the window, let go and watch it vanish into a puff of smoke.
