Uncomplex has released Mailplane 3.0.1, a maintenance release to the Gmail-specific mail client that revises keyboard shortcuts for opening mail due to a change that enables shortcuts to work in reply mode. The previous Mail > Open option has been revised to Mail > Open Conversation (Command-]), while Mail > Open In New Window has been added (Command-O). The update also lets you hide the tab bar, fixes an AppleScript issue with paragraphs in the mail body, squashes a bug with downloaded attachments containing special characters in their file names, and ensures that opening a file dialog no longer crashes the app in Mac OS X 10.7 Lion.

Create Rules Based on Entourage Messages
When creating rules in Entourage 2008, you can save some time by selecting a message like those you want the rule to work on before defining the rule. That way, when you add criteria to your rule, Entourage fills in the data based on the data in the selected message. So if you wanted to filter messages containing TidBITS, you could select an issue and add a new "From Contains" criterion to a rule. Entourage will automatically fill in the email@example.com address in the criterion.
