title: Split pane to cwd
body: <p>I often want to start a persistent process from a particular directory and be able to monitor it, while still keeping a command line in that directory for other commands.  My current workflow is to <code>cmd + shift + d</code> to split panes, but the cwd of the new pane is back at home, and I need to cd back to where I was.  Is there a good way to split panes and automatically set cwd of the new pane to the same directory as the pane it was split from?</p>
