ExpanDrive has released version 2.3 of its eponymous utility for making remote FTP, SFTP, and Amazon S3 storage act like local disks. The only major new feature in this release is full support for Mac OS X 10.7 Lion, but, over the last couple of updates, the company has been busy improving the speed of browsing and editing files, tweaking its caching algorithms, and fixing numerous bugs related to areas of functionality that range from authentication to remote synchronization.

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.
