I love leopards new sleek look, but I wasn’t too happy when I saw that aqua was still around, and googled around till I found an interesting post on a forum that describes how to change your scrollbars in leopard to match iTunes.
It looks awesome and works perfectly, You’ll need admin access to whatever Mac you’d like to do this to, but all you have to do is delete 1 file and replace it with another, Restart or kill finder and viola! brand new scrollbars for your mac!

To add a nice hover effect to the icons in the stacks pop up enter the following code into your terminal ( applications/utilities/terminal.app)
defaults write com.apple.dock mouse-over-hilte-stack -boolean YES killall Dock
To Remove this Stacks hover effect enter the following terminal command:
defaults write com.apple.dock mouse-over-hilte-stack -boolean NO killall Dock
Here’s a preview of the magic at work.It’s also important to note that this only shows when you navigate your stack pop up by keyboard.

If you would like to set a specific icon for each stack instead of the default stack pile of icons, Stacks in Da Place from Eagle-of-liberty was developed with you in mind, It’s a great little piece of donationware that lets you use any icon you want for any stack, easy as dragging and dropping the icon you want.

If you’re looking for a way to remove the 3d styled dock from leopard, Here’s how you do it
First open terminal and enter this command:
$ defaults write com.apple.dock no-glass -boolean YES
To change it back simply enter :
$ defaults write com.apple.dock no-glass -boolean YES
Then Type:
killall Dock
The dock will then restart with a new 2D style dock similar to that of Tiger, but slightly better looking in my opinion.
If you’re not up for entering terminal commands and would like to achieve the same thing you can also download the DockDoctor widget from innermindmedia and it’ll let you toggle back and forth with 0 effort right from your dashboard.

I find Leopards new Stacks feature incredibly useful, and fun to watch at the same time! Here are a few tweaks to help you make the most of stacks.
You can add a ” Recent Items” Stack to your dock by entering the following in terminal ( You can find terminal in /applications/utilities )
defaults write com.apple.dock persistent-others -array-add '{ "tile-data" = { "list-type" = 1; }; "tile-type" = "recents-tile"; }'
Once the stack appears you can right click it and select its type, and a few other features. To add a nice hover effect for the icons in a stack when expanded, Enter this line into the terminal
defaults write com.apple.dock mouse-over-hilte-stack -boolean YES
Type the same, with NO at the end to reverse this effect.
If you don’t like stacks and the reduced folder browsing capabilities, you can download Quay, Developed by Rainer Brockerhof, It Allows you to add your drive, or folders to your dock and browse them via a menu just as you would in OS X Tiger.
