If you have experienced the power, capability, and speed of kst and then set out to build something better plotjuggler must be amazing!
I am not sure of the development status of kst these days I think it does everything’s it’s authors need it to do. Airbus may have moved on to an internal tool. The list is very quiet. So hopefully it doesn’t disappear but I will surely check out plotjuggler.
There may be a market for you to sell it to scada and HMI companies like Rockwell AVEVA Schneider etc since many of them have pretty old school built in plotting functionality
But of course I am biased, as author of PlotJuggler ;)
