As it turns out there is a secret stack view in Snow Leopard that modifies the list view option for stacks. Below is a video showing the before and after. It also shows the transitions in slow motion.

To apply this view enter the following into Terminal:

defaults write com.apple.dock use-new-list-stack -bool YES

Than:

killall Dock

This will change the view and restart the dock.

We all love our Macs but there are always a couple small “features” that we could all trive without. Here are a few annoying ones and how to stop them. Be sure to share yours as well.

1. Stop obnoxious Bouncing Dock icons (Original Post)

fire up Terminal (Applications/Utilities/Terminal) and type in the following and hit enter:

defaults write com.apple.dock no-bouncing -bool TRUE

And then type in the following to restart your dock:

killall Dock

From now on you will not be plauged by the bouncing icons!

And for whatever reason you want to turn it back on you can enter the following into Terminal:

defaults write com.apple.dock no-bouncing -bool FALSE

and then

killall Dock

2. Disable flash or countdown in Photo Booth

Disabling flash in PhotoBooth is really easy all you have to do is hold the Shift key while you click to take a picture and the screen will not flash white.

Disabling the picture count down in PhotoBooth is just a matter of holding down the Option key while you click to take a picture, your photo will take immediately.

If You combine the keystrokes by holding down Option-Shift, you’ll immediately take a picture without the flash.

3. Toggle hiding the Dock using the keyboard.

A keyboard shortcut I use multiple times a day is Command + Option + D.
This will toggle hiding the dock. Great for anyone working with large windows and applications.

UPDATE (6-10-2009) Safari 4 have been updated for Snow Leopard and no longer has the tabs on the top.

Safari 4 Has some problems. We know this but at the same time Safari 4 offers us some more speed and flexibility. So rather than go back to previous versions here are 3 ways to bring back functionality from v3 but keep the speed and search-ability of v4.

Resources Mentioned in Video: Safari 4 Buddy – Free application Secret Safari 4 Menu – Menu File for Safari 4   Terminal Commands: 1. Move Tabs to bottom

$ defaults write com.apple.Safari DebugSafari4TabBarIsOnTop -bool NO

2. Loading Bars & Circle When both set to NO it restores the blue loading bar behind the URL. Also puts a page loading spinner in the tab itself, which looks odd with the new tabs:
 

$ defaults write com.apple.Safari DebugSafari4IncludeToolbarRedesign -bool NO
$ defaults write com.apple.Safari DebugSafari4LoadProgressStyle -bool NO

        3. Switch off the new URL autocomplete menu and go back to the original one

$ defaults write com.apple.Safari DebugSafari4IncludeFancyURLCompletionList -bool NO

4. Turn off the new Google suggest menu

$ defaults write com.apple.Safari DebugSafari4IncludeGoogleSuggest -bool NO

5. Remove CoverFlow from the Bookmarks view entirely        

$ defaults write com.apple.Safari DebugSafari4IncludeFlowViewInBookmarksView -bool NO

        6. Disable the dimming when clicking on a Top Site

$ defaults write com.apple.Safari DebugSafari4TopSitesZoomToPageAnimationDimsSnapshot -bool NO

7. Disable Top Sites feature completely

$ defaults write com.apple.Safari DebugSafari4IncludeTopSites -bool NO

8. Undoing changes Just run the defaults command with the delete flag for the appropriate key you wish to delete.

$ defaults delete com.apple.Safari <key>

Here are 3 quick ways to customize your Stacks appearance.

Custom Stack Overlay Icons

There is an easy way to take the default appearance of your dock stacks and optimize them for elegance and clarity. All you need are some icons like the ones below.

Download yours here

Once you have the icons you would like to use, name them according to the stack they represent and add a space before the name. This way the stack overlay will stay at the top of the stack.

Than just drop them into your folders. So the download icon goes in the downloads folder. You will want to edit the name of the stack icon and put a space before name. This way the icon will always stay at the top of the stack.

Adding Draw frame (Leopard Only)

To do, go grab a free copy of SuperDocker. As you know from reading the other custom Dock and Stack posts, this application is great for easily and safely customizing the Dock and Stacks. So once you open up SuperDocker, navigate the “Stack” settings tab and there you will find a check box to add a draw frame. And your done!

Removing Stack Background Grid (Leopard Only)

1. Fire up Finder
2. Navigate to Macintosh HD/System/Library/Core Services
3. Look for Dock and control-click on it
4. Choose Show Package Contents from its contextual menu and then go inside Contents → Resources Back up and delete from that folder all of image files prefixed with “stackbackground-”
5. Use your Terminal to restart Dock by executing command line: killall Dock

Changing Stack Background Color (Leopard Only)

Fire up SuperDocker again and in the “Stacks” there is an option to change the color or the background grid. I now it’s complicated, just breathe ok.
