I loved the combat and ship outfitting last time I played a few years ago but remember finding it a massive chore to keep supplies/fuel stocked up as they'd run out so quickly, has that system changed at all?
Nope.
It's manageable, but it remains a constant chore. Furthermore, there are intentional shortages of supplies and fuel. In the version I played (there's been a major update since then), one planet in one system produced most of the fuel, and all the rest of the planets in the entire game universe produced fumes by comparison. If you side politically with factions other than that one faction, then procuring fuel for very large fleets becomes double the chore, even with commander skills that reduce fleet fuel consumption.
I mentioned this on their official forums, but the official forums are populated by people who've been playing the game for thousands of hours, and don't tend to be able to see from any viewpoint other than the viewpoint of a longtime veteran.
