It would be really helpful if developers could change the colour of the white range numering to something that stands out more like bright yellow. I find it hard to range find when using mortars or flying because the white numbers get lost in background and makes it hard to use effectivly.
Also if you could have something that indicates the radiowaves/artillery are busy or in use by someone else, it would be helpful. It is annoying to go all the way through targeting a strike repeatedly only to keep being told lines are busy and your squad is getting picked off in the meantime. Perhaps have it indicate the line is busy without having to go through the whole thing.
