* Auto local address selection: find a port available and start listening to it, so the -local flag doesn’t need to be given every time you run the app.

* Create multiple tunnels using a single ssh connection: multiple tunnels can be established using a single connection to a ssh server by specifying different -remote flags.

* Aliases: save your tunnel settings under an alias, so it can be reused later.

* Leverage the SSH Config File: use some options (e.g. user name, identity key and port), specified in $HOME/.ssh/config whenever possible, so there is no need to have the same SSH server configuration in multiple places.

* Idle clients do not get disconnected from the ssh server since Mole keeps sending synthetic packets acting as a keep alive mechanism.

* Auto reconnection to the ssh server if the it is dropped by any reason.
