I’ve been using Quicksilver for its clipboard manager–among other things. If you’re a developer, having a clipboard history that is easy to access adds incredibly productivity. I was having an issue where the clipboard manager would suddenly appear out of nowhere, randomly. I was able to implement a cludgy fix by docking the clipboard manager on the side of my screen. Just leave the window touching a side, and it will slide and dock automatically.
Here’s where I found the information: //code.google.com/p/blacktree-quicksilver/issues/detail?id=44.
