Uncomplex has released Mailplane 3.1 with a number of improvements to the Gmail-specific email client. The update now enables you to switch between an unlimited number of Gmail accounts (previously, Mailplane limited you to 10 accounts), adds an option to suppress notifications of unread messages in the menu bar and the Dock (if you don’t need to see the count of unread messages taunting you everywhere you look), automatically hides the Gmail header when printing a message, fixes the Quick Look previews of Office documents in OS X 10.9 Mavericks, and fixes a bug with Google’s recently updated sign-in interface.

Spacebar Magnifies Photos in iPhoto '08
In iPhoto '08, you can choose whether double-clicking on a photo will edit it or magnify it. I prefer my double-clicks to edit photos, but every now and then it's nice to magnify a photo. To do that, even when double-click is set to edit, just select the photo and press the Spacebar.
