With Sparrow 1.2, the email client gains connections with Facebook (for displaying friend pictures and adding friends from within Sparrow), a unified Inbox, support for Gravatar, Subject-based threading, the option to create a new message by Control-clicking Sparrow’s Dock icon, and localizations in eight languages. A variety of bugs have been fixed as well. I still can’t consider Sparrow as a usable Gmail client due to its newest-first conversation sorting (so threads must be read from the bottom up) and extremely slow load performance for message bodies. A free Sparrow Lite works with only a single Gmail account. ($9.99 via the Mac App Store, free update, 11.9 MB)
View Full Threads in Apple Mail
Many users are aware of Apple Mail's message threading feature, which highlights related email messages within the Inbox. However, many people don't know how to view both sent and received messages within a thread at once. To do so, first enable Message Threading under Mail's Viewing Preferences. Then, Command-click both the mailbox containing your threaded messages, and your Sent box. Now you can view both sent and received messages within the thread simultaneously.
