Some of these may have already been suggested. If so, please let me know. Difficult to wade through nearly fifty pages of thread when I have limited time.
This thread falls under the Navigation/Exploration category, mostly, as I'm on my first trip outbound. I'm only about 1200LY from civilized space. I'm relatively enjoying it, but playing smart requires a lot of excess time in the Galaxy Map staring at each individual star for both fuel and multi-star issues. In keeping with cutting down time spent in UI and maximizing time spent flying:
Multi-Star Display
Currently, multi-star systems only show the secondary stars when targeted. Simply focusing on the system should suffice for displaying additional stars within a particular system and cut down on time spent checking entire route.
Separate Route Tab
Once you plot a route, a route tab lists all your destinations in one column and the star-types detected in another column. You can click each line to zoom in on a particular star for checking the secondary stars for safe approach vectors. The list would also tell you the star classes so you can plan your refueling stops much easier.
Alternate Vector Reroute
Currently, if you have a route planned and find yourself needing to target an off-route system for refueling or entry vector, your entire route disappears. Adding in some kind of "reroute" feature, even if you had to pick the star to manually add on to your route, would help immensely when you're in the deep and you lose track of stars past the alphanumeric soup that identifies them. You get to keep the original route you plotted, but add or remove destinations as needed. Could be managed as part of the Route Tab.
"Visited Systems" View in Galaxy Map or list in a menu
In addition to lists likely proposed elsewhere, a filter for systems you have visited would mostly be nice to have, more than anything.
"First Discovered" View in Galaxy Map or list in a menu
I know I'd love to remember the places that I am credited for getting there first.
Again, sorry if these have been addressed elsewhere. I don't recall seeing these listed in the first post.
