First, tums up to you great effort.. Rellay helful stuff, by which I am able to overview very simply nad visibly all my network..
Stuff I am missing..
SSH client in right mouse click - very unconfortable to use external client.
Ping watchdog stuff is still very weak. What I know is just if ping passed or not. Which makes me really happy, but as network grows, latency control takes it place - because of VoIP and QOS utils.. Then think about some graphing which uses for example cacti with RDDTOOL - really impresive stuff, where you can handle avverage, max and min ping and its magazine packet loss. You know some time you loose one of your locatin knowing nothing about reason, and that can help..
