Tmux has an option to have the #{pane_current_path} as a name for the current pane in the status line. This is great but has two short falls for me:

1. $HOME is not displayed as ~.
2. I only really need the last directory name, not the full path from /.

Is there a Tmux command that does this?

Bonus points if it works with powerline as well.
