The real Leopard show-sto er? Developer goodies that weren't on stage

Reports are surfacing on the web that, while everything A le showed on stage at WWDC 2006 was exciting and purty 'n all, the more exciting attractio are what wa 't shown on stage. AeroExperience, a Vista developer resource site (of all places), claims to have an exclusive list of many of the underlying changes, newly introduced APIs and other developer goodies that might simply not have been prime fodder for the news and PR otlight se ion of the keynote.

It's a pretty lengthy list, so here are some of the highlights for you cliffnote readers out there:

• Leopard will feature resolution-independent user interface and there are several functio to get the current scaling factor and a ly it to pixel measurements (we've mentioned how cool this is before, and so has Mr. Gruber).
• Addre Book adds su ort for sharing accounts, allowing an a lication to restrict content according to user (.Mac already does this, so I'm wondering if they mean some kind of framework or protocol is in place to open this up to something like WebDAV or simple FTP).
• Automator includes a new user interface and allows things such as action recording, workflow variables and embedding workflows in other a licatio .
• Time Machine has an API that allows developers to exclude unimportant files from a backup set which improves backup performance and reduces ace needed for a backup (I was curious about how Time Machine would handle 'usele junk' types of files myself).
• Carbon, the set of APIs built upon Cla ic MacOS and used by most 3rd party high-profile Mac OS X a licatio , now allows Cocoa views to be embedded into the a lication. This could provide a licatio like Photoshop and Microsoft Office acce to advanced functio previously only available to Cocoa a licatio .
• Text engine improvements include a systemwide grammar checking facility, smart quote su ort, automatic link detection and su ort for copying and pasting multiple selectio .
• Mail stationery is open to developers, allowing any web designer to create fantastic-looking Mail templates, with defined areas for custom user content (bring on the stationary plugin packs!).
• A new framework is included for publishing and su cribing to R and Atom feeds, including complete R parsing and generation. Local feeds can be shared over Bonjour zero-configuration sharing and discovery (I su ected something like thi sounds like Safari and Mail.a might share the same R database, as can other a , so users don't have to waste time exporting/importing between R a ).
