There’s a few things on my Mac that I can’t live without, that do actually make my life easier and more productive. Default Folder is a godsend when navigating open and save dialogs. DragThing is by far the best ‘launcher’ application out there. SnapzPro is something I use nearly everyday for making screenshots in various formats. Finally a cool little contextual menu plug-in is A Better Finder Creators and Types - changes the creator and type of any file to anything you want, essential for when you get PC files sent over email.
