Imagine this, your player faction controls 5 different systems. You know that by running EDMC and navigating to each system, you can update INARA with that system's faction influence information. Currently, you need to follow the process of jumping into system "A", opening the galaxy map, route to system "B", jump to system "B", open the galaxy map, route to system "C", etc. Wouldn't it be MUCH easier to simply be able plot a route from A, to B, to C, to D, etc. before you take that first jump? Then, each time you jump into a given system, all you need to do is use the keybind for "select next system in route" and make the next jump.
This feature has much wider uses than my simple example. Think of those times when you're trying to navigate to Beagle Point in a Sidewinder on a dare, and you have to manually route around a particularly empty portion of the galaxy. Or, on the road to riches, being able to manually plot a route of up to 20 systems. Or, you are making a trade loop. Or you are visiting all the engineers. Or, you are wanting to travel from The Bubble to Colonia, but have a couple of sight-seeing detours that you want to take along the way. I'm sure that many commanders can come up with thousands of useful examples where this feature would be beneficial, this is just what I can come up with off the top of my head.
Elite Dangerous already has an amazing route-plotting utility. The ability to customize it, such as adding detours, or to simply create your own route with multiple jumps, would take it to the next level of usability.
