I think this will become a module at some point. Seriously. Right after we get the Trade Module that automatically picks the best goods and route for you, and the Combat Module that takes care of all that pesky fly by skill thing. All of those plus your idea and docking computer and we're all on easy street my friend! Oh yeah, bring it on!
Auto pilot is one of those requests that a lot still consider isn't likely to happen.
In the meantime, 100% throttle until 7 seconds away, then 75% throttle until about 6-7 ls distance, then 100% throttle.
If you suffer a stutter and your "time to target" falls below 6s, point your nose down at 75%throttle and wait to see the "slow down" disappear (if you're quick enough, it won't appear at all, so just wait for the tell tale sound of your engine giving).
If you hit a gravity well, your "time to target" may increase above 6s. Feel free to throttle to 100% until it drops back to 6.
6s is the magic number. If at 6 throttle down quick. Any higher, make it faster.
Now, to me, that's a very quick summary of it. But there's a reason it's more detailed than "point and sit".
I get it the "mini game" is annoying for some. But if there was no meaning to the use of throttle control, it would be even more mundane. The fact is, if you know all the tricks, you can get from a to b faster than those who don't.
If that sort of detail doesn't interest you, then that's fine. But I like it.
