Having more bank accounts would help with planning ship repairs. If i had a bank account that labeled towards say a ship. I could transfer money to that account to go towards ship repairs/fuel.
I would find this easier than keeping track of it in a spreadsheet, Incase I fall to ruins by purchasing other products and can’t afford ship repairs or fuel.
IMHO it’s a super niche kind of feature with a very low ratio of usefulness to added complexity and dev time. What I’d recommend (aside from just doing that in a spreadsheet like everyone else) is to allocate this money via CX orders. Put a bid on that LHP, the money is subtracted from your account and is labeled in CXOS (“this is what I’ve saved towards that ship”), and should someone sell you the stuff, everything balances out neatly.
