Postbox has released version 3.0.8 of its eponymous email client, using the integrated graphics processor exclusively on MacBook Pro models that have dual GPUs in order to reduce power usage and thus save some battery life. The update also adds a Run Filters on Folder toolbar button, ensures that Notification Center alerts link directly to messages, displays the account name next to the folder name in the message pane, and adds automatic account configuration support for iCloud email accounts. Plus, it fixes an issue with Growl integration, a crash when indexing, and a crash when importing from Thunderbird. ($9.95 new, free update, 21.5 MB, release notes)
Avoid Simple Typos
If, like me, you find yourself typing 2911 in place of 2011 entirely too often, you can have Mac OS X (either Lion or Snow Leopard) fix such typos for you automatically. Just open the Language & Text pane of System Preferences, click the Text button at the top, and then add a text substitution by clicking the + button underneath the list. It won't work everywhere (for that you'll want a utility like Smile's TextExpander), but it should work in applications like Pages and TextEdit, and in Save dialog boxes.
