`show-config` should show configuration
qs show-config cfg-name
should display configuration:
$ qs show-config gmail
protocol: mail
username: blah@gmail.com
password: ****
host: smtp.googlemail.com
port: 465
contacts:
- me: blah@gmail.com
- anna: anna@example.com
Something like that (maybe make contacts a comma-separated list so they'll be easily greppable).
