Hopefully this will be included, and I'm just behind the times, but I'd really like to have either a Tab / button to have a look at financial performance, position and current in / outflows. While I know this is not an economics sim,, managing money is an important part of any such strategic game.
I suppose it wouldn't have to be a button, It could be a monthly / Yearly pop-up (kinda like the interception one) where a review of performance is presented to the player. It should show the finances (income, spend) the current level of alien activity, the relations with the different sectors (movement) and the stats of intercepts / ufo's downed / killed / captured / losses.... et centra.
This idea was inspired by this Screenshot, called "Funding meeting".
