the "tls_client_cert" and "tls_client_key' are useful
it will allow user put the cert and key files where he wants.

For a non-root priviledge, could not get a system session,
so "default_session_type" is meaningless, and actually
you already specified it in "default_uri".  :-)

it will be convenient for user who doesn't want to always input
characters. However, think there are not many configurable
preferences currently for the clients.

Anyway, I think it's a good idea.
