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)
iCal Alerts You Can't Miss
Did you miss that tiny little iCal alert dialog? Use a more prominent Open File alarm.
First save an image, text file, sound, or movie that will really fill your screen and grab your attention.
Select an iCal event and choose Open File as the alert type. Choose your unmissable file as the one to open.
Set more alerts with more files to open for the same event if you like. You won't miss an appointment with one of these alerts!
