Running SL, I had burrowed down to find a folder in the darkest, deepest reaches of my HD, where I wanted to save a new file. I also had a save window open, but I didn't want to drill down in the save window, duplicating all that hard work it took to find the target folder. So, in the finder, I tried dragging the folder icon at the top of the target folder's window to the save window of the app, and the save window navigated to the target folder. How long have I been oblivious to this?
