Hmmm maybe an alternative could be to display a small number the same way core damage is shown?
Right, that's what I meant about this being unnecessarily distracting feature because it's to reflect a simple piece of info that's already reflected elsewhere (and should generally be obvious since you're running over it on the map) and will cover other much more important info, like objects and where you're going etc.
This number could be the percentage of remaining matter (and maybe energy/core) after the action, instead of the absolute number. Not sure if map can display a percentage sign, though it's probably unneeded if it's an advanced option.
Yeah total percentage is perhaps a more interesting alternative (and certainly '%' can be displayed, it's just a regular old character like any other, and we've got many on-map displays that already show this).
In general you're supposed to kinda keep an eye on your resource levels every so often regardless of what's going on, which I feel is a better approach--getting used to doing that instead of having it right in your face all the time,
but that said some people do have a lot of trouble getting used to that, or even experienced players sometimes forget at certain opportunities... That said, it's mostly about values going
down that people forget, rather than going
up, which again should be pretty obvious since you see it on the map as you're moving over it (and the brightness of the matter also tells you approximately how much is there, in case you hadn't already noticed that bit).
Meh, in the end it's definitely an optional sorta thing which I don't feel would be a net positive as far as default behavior, but we'll see.
