Hi,

I'm using urxvt as default terminal with zsh but your script didn't initialy work with my architecture.
To make it works I had to modify the python script line 49:

return ['urxvt', '-hold', '-e', 'zsh', '-c']

It creates a new terminal embedding a holding shell (was initialy closed immediately) session.
Then '-c' runs the command in it (only '-e' doesn't work).

Hope this will help for an update,
Regards,
