I'm beginning to like Leopard as time goes by and discovering a lot of great things with this latest OS from Apple. And so if you find any features that you stumbled upon, feel free to share: Here are my contributions: 1. You can turn off and on the 3D effect of the dock automatically using Automator by doing the following: a. Copy both scripts to a separate folder. b. Drag the folder to the dock to form a Stack. c. Then click the Automator script to change the look of your dock easily. 2. Change the color of the dock a. Ensure that you have write access to System/Library/CoreServices/Dock.app/Contents/Resources b. Backup the original files of frontline.png, scurve images and indicator images. c. Create a different color scheme to replace the original png files. d. In terminal, type killall Dock then press Enter. Original 3D dock: Modified 3D dock: I'm in the process of coming up of an Automator to automate the process. [Thanks to Dan Lidral-Porter for the idea] 3. Running out of space in your dock? The solution is to add those certain applications to the header bar of the finder window. I haven't tried this while I was still using tiger.
