I'd love to see a method of calculating or estimating distances within the game. This most commonly pops up when I'm building a network of airbases but I'm sure could be handy elsewhere. Usually I try to approximate it with IRL objects held up to my phone or computer screen, but multiple times I've built airbases thinking they were properly distances only to find out one was like 2km too far and my planes couldn't make the flight. To avoid that sometimes I'll wait until planes arrive at a base so I can see their range, then build the next base, then move them to that base, then build the next... but that's incredibly slow and tedious.
It could be as precise as showing you exact distances between two points (e.g. province centers when you're building airbases) or could just be a scale display in the bottom right that adjusts as you zoom in and out which could help with approximating distances.
