I think some of the old VB mechanics would be good to re-add. For example, I have a group of gas harvesters, and I'm building new ones constantly. They're all set up as tankers, and have refuelling modules. But the ones that have spent more time on station keep filling up more, and I don't know how to equalize fuel between them so that it can avoid having a couple of them hit 100% while others are at 12%. I tried experimenting with refuel fleet commands, but it just moved the top two on the list from 50%/50% full to 10%/90% full. (I suspect that I can start actively tweaking the minimum loadouts on each class, and that'd help a lot, but it's a pain in the neck).
Get that stuff sorted out, and I'm less worried about the new mechanics.
