Hello Frontier! I'd like to offer a couple of suggestions for the HUD UI.

(Yeah, I know, I think I might've made the arrows a bit huge, but you can't miss them, right?
)
Both of these suggestions only appear with the target system panel that shows up before a jump, so neither of these is persistent and doesn't add more clutter to the usual layout.
1. STAR TYPE ICON -- Color and letter coded. I'm aware that this does show up in the info panel, but this icon should make it easier to deliver the information at a glance.
2. FUELED/UNFUELED JUMPS REMAINING -- I sometimes struggle to remember how many jumps I can still make with available fuel, and it takes quite a while to pull up the galaxy map and count the 'broken line' jumps, not to mention the nav panel only shows you the total number of jumps in the route. So these two numbers show up only when a route has been planned: the number on the left indicates jumps remaining with available fuel, while the other one denotes total jumps in the route. (In this example it's 3/5; a fully fueled route should show up as 5/5, etc.) I know that the 'abort jump' message appears here when needed, so that should override the jump numbers whenever necessary.
Hope you like these and find them useful
