Drfiters Longer Wakes Mod works, as does Sober's 3d Waves. Tikigods Engine Telegraph Mod.
There are a few ones that don't work, the Spysat mod by danlisa ( shows all ship, convoy movement ) but he is working on that for the 1.02.
Lots of sub-skin mods out there.
I have not played GWX 1.02 enough to see what other's may or may not work, but I am sure others have.
Good hunting
