Apple reports that it sold 2 million copies of OS X 10.5 Leopard in the first weekend it was release. With so many Mac users embracing the new operating system developers now have to tools to turn up the dazzle. We decided to check in with the application that started the trend toward flashy visual design on the Mac -- Delicious Library. Will Shipley and crew are currently hard at work on version 2 of Delicious Monster, which he says will "arrive in time for the holiday season," but we got a sneak peak at the latest build. Delicious 2.0 leverages Leopard's Core Animation goodness to offer up eye popping visual transitions -- shelves slide and shuffle as you change sort options, deleting an entry burns the book and info windows slide and rotate according to your preference. But this isn't a cosmetic release, Delicious 2.0 uses an SQLite database and is blazing fast compared to it's predecessors. It also packs in Applescript support, html templates for printing and exporting, as well as live browsing of your friend's libraries within the Delicious interface. delicious1.jpg cap: The first thing you're likely to notice is the absence of the sidebar with book detail information. Instead that same info has been rolled into a overlaid window that automatically picks the best location, though clicking on the black triangle allows you to move it around where ever you would like. delicious2.jpg cap: The item information panel contains the same information that used to live in the sidebar, but adds some new features like an option to add related items to your library. You'll harding notice it, but it'll save you some scanning time. delicious3.jpg cap: Delete an item from your library and slick new flame graphic will eat it up. delicious4.jpg cap: Your library contains a multitude of sort options and switching between them brings Core Animation to the fore as your library items slide and shuffle into the new ordering. delicious5.jpg cap: New export options allow you upload pre-formatted templates with all your library data to .Mac, iWeb sites, a local folder or any FTP account your might have (Transmit users will be happy to note that Delicious Library 2.0 automatically grabs your Transmit FTP bookmarks) delicious6.jpg cap: Delicious isn't just for physical media any more. Version 2.0 integrates with iTunes and automatically pulls in music, including album details and track listings, as well as movies and audiobooks stored in iTunes.. delicious7.jpg cap: Delicious 2.0 Pro will ship with a number of new export options including XML, Excel database, and tab-delimited files, as well as BibTex and Bibliography formated files for the scholarly among us. There will also be advanced import options as well. delicious8.jpg cap: The sort options extend to smart shelves as well, which means you can do advanced sort or just plain fun ones like sorting by cover color. delicious9.jpg cap: Delicious 2.0 can automatically find and add your friends libraries to your own, or you can specify a url and the Delicious uses Google in the background to lookup delicious libraries on the web and help narrow it down to the person you're looking for.
