I don't know how possible this would be, but adding an average credits per day option to the minerals section would help a lot, especially when you are looking to add new modules with high upkeep to your ship.

Calculating it would work something like 5 hours worth of mining all sold. This would also help people who are trying to figure out how long before they can afford a module or assist with base upkeep.

if you're over lvl 160-ish (or in other words, if you're getting aidonium from your shipments finally)... a reasonable yet slightly conservative value when converting mining per hour to credits per day would be to look at your mining per hour as millions of credits per day.... so if you have 10,000 mining per hour, you're getting (a little bit over) 10 B credits per day... on average...

since it's a conservative value it gives you a bit of a safety net in case you have a low aidonium streak for a while... while still being a close approximation that you can use for budgeting
