Sometimes there is no sound from some channel, and it just take long to check all kind if option down the sound chain to Figure out why. Whitout all of the information shown to you.
It would be very handy to right click a channel (vst for example) , to open a window that shows the whole sound chain of that specific channel.
This window will contain blocks , left to right, and each one will show midi or sound information, to see where does the sound go through, including effect. And where did it stoped.
This would help understand instantly what is going on that channel.
