|Subject: [PATCH] MoveStack patch
|
|This plugin allows you to move clients around in the stack and swap them 
|with the master. It emulates the behavior off mod+shift+j and mod+shift+k 
|in Xmonad. movestack(+1) will swap the client with the current focus with 
|the next client. movestack(-1) will swap the client with the current focus 
|with the previous client.
