Last time I checked you plot your route using the Galaxy Map. Typically by using search feature (or filters) to find the system you're after and then you twiddle with the Galaxy Map using HID of your choice and place a way point on the map. What the OP is asking for is being able to do the same thing with the surface map.
You say it's challenging and fun for you the way it is, I say: good for you, you'd be totally free to have your fun whichever way you want. Whips, floggers... ED Surface navigation. Complete freedom. And just think about how superior will you feel when doing so, compared to all those namby-pamby softies who are not playing your self-invented mini game!
See if you can come up with an argument that
doesn't create a doble-standard when applied to the docking computer.
I don't mean that glibly, or antagonistically.
You could say exactly the same thing about the DC.
Let's make the DC part of the "navigation system" too.
After all, you navigate TO a station in exactly the same way you navigate to a surface POI.
So, why does your ship stop "navigating" when you arrive at a station?
Why do you need a separate module for that last little bit of your journey?
Why
couldn't it just be built into the navigation system?
Well, that's already been answered.
It's because there's a trade-off between convenience and ship payload capacity.
You want convenience, you have to sacrifice some payload capacity.
ED has already shown us, in a heap of different ways, that if you want the best of one thing, you have to sacrifice the best of something else.
If you want the best shields, you (usually) have to sacrifice payload capacity.
If you want the best weapons, you have to sacrifice ease of use.
If you want the best ship agility, you have to sacrifice ease of control.
If you want the best jump range, you have to sacrifice survivability.
If you want convenience of docking, you have to sacrifice payload capacity.
All of those compromises
could be removed.
We could demand that every ship had 2 slots of the biggest size.
We could demand that every weapon came in fixed, gimbaled and turreted versions.
We could demand that the FA system allowed much more agility.
We could demand that jump-range wasn't affected by weight.
We could demand that the DC was integrated into the navigation system.
ALL of these things would improve "QoL".
Anybody who had made an effort to develop these things could continue as they currently are if they wished to.
The only difference is that their efforts would gain them no advantage over somebody who wasn't prepared to make the same effort.
Do you think that'd be a good thing?
I don't.
Which is why I think there should be
some kind of trade-off rather than just an arbitrary "dumbing down" of an existing system.
