It would be very helpful when the node would say how long the burn will be BEFORE it's getting executed.
Especially for very short burns this would help because you usually have to stop them very fast.
I accidentally staged before the execution of a node and the node didn't get updated. The burn time and start time were way of and I ended up in a wrong orbit.
I noticed this too.
And while editing nodes you also can't see the resulting ap/pe when hovering over them with the mouse.
You have to quit editing and then you'll see the resulting ap/pe.
