Uncomplex has released Mailplane 3.0.2 with the addition of a few welcome user interface changes. The Gmail-specific email client’s main window now displays your selected account in the window title (handy for those managing multiple accounts), enables you to assign a global keyboard shortcut of your choosing to compose a new message, and highlights Find results as you type. Other improvements include the capability to drop URLs into a message and drag blocks of text to another position. Finally, Mailplane 3.0.2 is ready for the upcoming release of OS X 10.9 Mavericks.
