Thank you all for your replies, I did not think I will get so many responses
From most of the comments I can see that it is a game element to plot your manuevers in real time. I guess after some time you gain the experience how to get into orbit the most efficient way.
For me currently what very frustrating is that after launching the rocket I have to check the orbital view, plot navigation trajectory, screw it up, delete the trajectroy, select another navigation node, plot a new trjectory, go back to the rocket and steer the rocket to target....but then your first stage ran out of fuel.....
As some of you have mentioned before, you see it as a game element, but I feel that slowing down time or have an active pause would help to put rockets more efficently to orbit as you have more time to tweak your trajectory.
And I guess in real life people also don't start to plan their rocket flight right after ignition
