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.

Viewing Wi-Fi Details in Snow Leopard
In Snow Leopard, hold down the Option key before clicking the AirPort menu. Doing so reveals additional technical details including which standards, speeds, and frequencies you're using to connect, as well as what's in use by other networks. With the Option key held down and with a network already joined, the AirPort menu reveals seven pieces of information: the PHY Mode, the MAC (Media Access Control) address, the channel and band in use, the security method that's in use, the RSSI (Received Signal Strength Indication) measurement, the transmit rate, and the MCS Index. In Leopard, some, but not all, of these details are revealed by Option-clicking the AirPort menu.
