To me, it's inconsistent for them to be pushing auto-saving/backup/versioning but also have auto-locking.
You clearly haven't thought this through very well. The lock feature goes hand-in-hand with autosave - it keeps you from wasting hard drive space on revisions that are essentially just unimportant changes in scratch work that you never save.
Returning to the title bar pop-up menu, the "Revert to Last Saved Version" menu item returns the document to its last explicitly saved state (i.e., what it looked like the last time the user typed âOES or selected the "Save a Version" menu item). "Duplicate" will create a new document containing the same data as the current document. Finally, the "Lock" item will prevent any further changes to the document until it is explicitly unlocked by the user. Documents will also automatically be locked if they're not modified for a little while. The auto-lock time is configurable in the "Optionsâ¦" screen of the Time Machine preference pane (of all places), with values from one day to one year. The default is two weeks. [You can also turn auto-lock off.] [cite]
Apple's push towards full-screen apps seems like a small step backwards... Apple machines now have too many kinds of applications (widgets, normal applications, maximized applications, these new full-screen applications, plus older 'full-screen apps' like front-row).
You misunderstand. They permit putting an application into full-screen mode. There is not a "new [kind of] full-screen application" All this is is OS-level support for what you already do with Firefox. Implementing this in the API rather than having each app provide its own improves consistency. And having the option to full-screen, e.g., the Terminal makes the computer MORE open, flexible, and powerful, not less.
But on a desktop or laptop, I'd rather see the scroll-bars. It gives you something to mouse towards and grab. More importantly, it gives you constant feedback about where you are within a document, as well as information about the size of the document.
The default setting, "Automatically based on input type," will use overlay scroll bars as long as there's at least one touch-capable input device attached (though the trackpad on laptops doesn't count if any other external pointing devices are connected). If you don't like this kind of second-guessing, just choose one of the other options. The "When scrolling" option means always use overlay scroll bars, and the "Always" option means always show scroll bars [cite]
