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)
Enter Dashboard, Expose, or Spaces Temporarily
Hold down F9, F10, F11, or F12 (or whatever you've set for the Expose and Spaces keyboard shortcuts) for a few seconds, and then release the key to enter and leave the appropriate mode without having to press the key again. This is particularly useful for Dashboard, in which you can check the contents of a widget and then return to your work with only a single key press.
