Snow Leopard UI changes
A number of minor but cumulatively important interface changes have been made in Mac OS X Snow Leopard, observes a Flickr user with access to the developer beta. Beyond some known tweaks, such as the addition of sliders for icon size, the software is also expected to warn users who have not created a password hint, and enable Quick Look within Open and Save dialogs, not just Finder. The System Preferences pane has meanwhile been rearranged, for instance splitting the Keyboard and Mouse sections, removing QuickTime, and moving Bluetooth under a new Internet & Wireless header.
Date and time options allow both figures to be shown in the Menu Bar, and timezones can now be set automatically, using data gleaned from Core Location. Some security features include the ability to permit signed apps to bypass the firewall, and separate the times when a Mac goes to sleep and asks for a password.
iCal has been given support for Microsoft Exchange accounts, while Address Book has been altered with settings for sync with MobileMe, Yahoo, Google and Exchange. Expanded connectivity includes scanner sharing, and automatic detection of wireless mice when opening the Mouse pane.
QuickTime X is newly capable of frameless playback, and even minor audio and video editing in the form of trimming. Some miscellaneous OS changes include split Terminal windows, the renaming of the Installed Updates tab in Software Update to Installed Software, and the introduction of global text substitution. The latter forces software to replace characters with preferred ones, such as the trademark symbol in place of "TM." Automator has been revised to rely on workflow templates, including a new Service type.
More details on Snow Leopard are anticipated at June's WWDC event.
