Finer Things in Mac

The Spaces overview lets you enter All-Windows Exposé mode. You can enter Exposé, then invoke Spaces, or invoke Spaces and then enter Exposé.  Either way, you’ll be able to see all your windows.
If you grab a window in this Spaces+Exposé mode and move it to a different Space, there’s another treat: the window will retain its [...]

In Snow Leopard, when multiple monitors are connected, Spaces now adds a one pixel line between the separate displays. This makes the two desktops easier to distinguish than in Leopard, where no such line existed.

As you can see, the context menu on the Dock blurs out the text behind it, much like Vista window management.

Editor’s note: Can anyone test this in pre-Snow-Leopard versions of Mac OS X? I’m not sure whether this is exclusive to [...]

If you click the dropdown menu next to a phone number in Mail, you can not only make a contact from it, you can also have it fill the screen by selecting “Large Type”.

This is useful if you need to call said number but won’t be right next to your Mac to do it.

If you want to rearrange the order of Apple’s menubar icons, you can do so by holding down the Command key while click-and-dragging the icon you wish to move. The only icon that cannot be rearranged is Spotlight’s. By moving the icon out of the menubar and releasing the mouse button, the icon will be [...]

Earlier versions of QuickTime played video in the icon in the dock.
QuickTime X doesn ot do this anymore; it just displays a static thumbnail when you minimize a video.

If you copy and paste a web page into a new Mail message, or use Safari’s “Mail contents of this page” feature, you can click on various sections of the site in the message and delete them. This is similar to Mail’s new ability to delete portions of a reply chain while composing.
