When the VNC session is disconnected (e.g. using VNC from home, put laptop to sleep and reconnect to work network), it would be nice to have a forced "reconnect" option.
I see the reconnect button sometimes after the connection has timed out but it seems to take quite awhile to realize the connection is broken. A force reconnect option would allow you to get the session back much more quickly. Currently I just have to kill the old client session and start a new one.
