I discovered some hidden user interface tweaks to OS X that really should’ve been enabled by default. I’ll list them out in order of decreasing awesomeness.

To do any of these, you have to run the Terminal application:

In the Utilities folder in Applications

1) Track information for iTunes dock icon.

So convenient!

This one is useful for obvious reasons. To enable this, simply quit iTunes and then fire up Terminal to enter the following:

defaults write com.apple.dock itunes-notifications -bool TRUE;killall Dock

Restart iTunes and the setting will take effect.
To disable, just enter the same command in terminal except change TRUE to FALSE.

2) List/Stack hybrid.

Hybrid!

By default, stacks was probably the most useless feature in OS X since they were introduced way back in version 10.5. Both fan and grid options really just impede navigation. The moment they enabled a list view, i switched back. And now I’m using this hybrid stack. Works just like a list but with the visibility offered by stacks.

defaults write com.apple.dock use-new-list-stack -boolean YES;killall Dock

3) White cursor highlights in stack.

Highlights!

This one goes hand in hand with number 2. It doesn’t add anything too useful but it looks nice.

defaults write com.apple.dock mouse-over-hilite-stack -boolean YES;killall Dock

Pretty nifty right?
