[xmonad] Reset layout to default on last window close

Hello, I want workspace layout to reset to some default once last window is closed. Quick glance though Xmonad-related modules names didn't give me any hints on what hook (or some other facility) to use, so I'm seeking your advice, fellow Xmonaders: how can I accomplish that? -- Regards, Alexander Batischev 4096R/0C8BFD03 CE6C 4307 9348 58E3 FD94 A00F 3569 61A2 0C8B FD03
