Nice idea!

Can you imagine how awesome a GUI version would look, with a simple click interface to zoom in and choose your inputs?

However, I suspect a computer will always be able to select outputs more 'randomly' than a human...so that degree of control may actually work against it's intended purpose :(

ok

One less thing in my todo list :)

@NanoAkron It would be great if the GUI can provide a similar functionality with better visuals. I don't have experience with Qt, so hopefully someone like @Jaqueeee will make it happen soon^tm :)
