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.

Option-Click in Scroll Bars for Jump Scrolling
In Mac OS X in general, and thus in most native Mac OS X applications, hold down the Option key and click anywhere in a window's scroll bar to jump to that spot (rather than scrolling one screen). If you like this behavior, you can make it the default in the Appearance preference pane. For "Click in the scroll bar to:" select "Jump to here."
