I've fiddled around with the unit and nav icons to make them not superimpose themselves over everything like they usually do. Unit icons have been redesigned, the X and the giant light bulb are gone. The arrows on the screen edge indicating the position of planes around you are transparent now.
Nav icons have been resized to be smaller and made transparent.
Unfortunately I have found no way to manipulate the font for distance and name.
Unpack into the Rise of Flight folder or make a new folder in JSGMEMODS and unpack therein for activation.
Added a plane-icon-only-variant as well as an empty 1-pixel-file. If you prefer your own choice of icons to disable, overwrite unwanted icons with this empty one.
Each unit icon and also the arrows come in black, blue and red. Here's a list:
[Update 2:]New unit icon file names with Ver. 1.029!
f101-0, f101-1, f101-2.dds - Plane
f102*.dds - Balloon
f103*.dds - Ground unit
fa*.dds - Arrow
Nav icons also come in three variants. When an icon gets activated in game, it flashes through the second and third variants. The list:
f11*.dds - Waypoint
f12*.dds - Target (mission objective)
f13*.dds - Area of activity (patrol areas & stuff)
f14*.dds - Escort objective (blue shield)
f15*.dds - Landing site
