Uncomplex has released Mailplane 3.3, which now automatically signs out accounts with empty passwords as well as clearing cookies and caches when quitting. The Gmail-specific email client also enables you to preview and download attachments shared from Google Drive, plus open Google Docs in an external Web browser. The release also fixes the bulleted list insertion (Command-Shift-8) so that it works in a pop-out window, prevents inline images from being inserted into plain text messages, opens Google Hangouts if opened via a Google Calendar event, and ensures that print works if a language other than English was selected.

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.
