Using Stacks for Screenshots
The default set of stacks in Leopard do a pretty good job of keeping your desktop clean of downloads, but for me, the real challenge of keeping things tidy comes from the multitude of screenshots that I take everyday.
Creating a stack for screenshots is the logical answer, but because they are saved to the desktop by default, it’s impossible to do this without first making a minor tweak to how OS X handles them. There’s probably several ways to do this, but I found a free application called deeper which seems to work pretty well.
Once you’ve changed the location, it’s as simple as dragging that new folder into your dock and tweaking the stack preferences to “Sort by date added”.
Voila… now all your screenshots will be easily accessible in any application, and your desktop will be a whole lot cleaner.
