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)
Mac OS X Services in Snow Leopard
Mac OS X Services let one application supply its powers to another; for example, a Grab service helps TextEdit paste a screenshot into a document. Most users either don't know that Services exist, because they're in an obscure hierarchical menu (ApplicationName > Services), or they mostly don't use them because there are so many of them.
Snow Leopard makes it easier for the uninitiated to utilize this feature; only services appropriate to the current context appear. And in addition to the hierarchical menu, services are discoverable as custom contextual menu items - Control-click in a TextEdit document to access the Grab service, for instance.
In addition, the revamped Keyboard preference pane lets you manage services for the first time ever. You can enable and disable them, and even change their keyboard shortcuts.
