Some of us here at TidBITS were very bummed to read Steven Vaughan-Nichols's ZDNet blog post bemoaning the 10 January 2011 shutdown of Xmarks, which synchronizes bookmarks between different browsers, including Safari, Firefox, and Google Chrome, even across operating systems. We never got around to writing about Xmarks in TidBITS, but that was merely a lack of time, not a lack of enthusiasm. If only other synchronization services were as good! [Update: Since we initially linked to Steven's post, things have changed and it sounds as though Xmarks may have a second chance; see "Xmarks Is Dead. Long Live Xmarks?" on the Xmarks blog mentioned in the comments for details.] follow link
Compare More Easily in Apple Mail
In Apple Mail, if you need to work back and forth between two different views of Mail's mailbox contents, you can do so quite easily. For example, you might want to look at a mailbox holding all filtered-in sales orders from the past week while also looking at a smart mailbox showing unanswered customer questions.
To avoid constantly clicking between mailbox views and losing your context each time, choose File > New Viewer window to get a second window and then arrange each window as desired.
