For those who read Gmail via its Web interface, including in Mailplane, Google has released a Gmail Labs feature called Preview Pane. It gives Gmail a vertical interface with labels on the left, a vertical list of message summaries in the middle, and the main conversation display pane on the right. It works best with wide screens, though if you have a tall screen, you can switch it to a horizontal split instead of a vertical split. The approach is much more like Gmail’s tablet interface, and in turn like Mail on the iPad. follow link
