Dockey makes changing some of the more advanced Dock preferences as easy as clicking a button. With integrated preview, you can see how it would look and feel like and save changes you're happy with the result.
It just works. A small change, but it really improves my productivity.
I was aware you could do this using terminal commands, but I could never be bothered to change it so I just kept the dock. This was exactly what I needed to see if I could go full-time without the dock and have that coveted extra screen real estate. However, I think this should be like a £0.99p app, I feel bad when someone creates this and I get to use it for free.
