Love the mod can't wait to see what you're going to do with it, I have some thoughts if ur interested. E-75 and E-90 are more heavy tanks I think those could be renamed to E-50M and E-60 or E-55 (the numbers a related to tons) also the Maus and E-100 was kind of a completely new class of heavy tank, like supper heavy, so idk if it's possible for them to have a there own branch also the Lowe/Panzer VII is more a heavy tank or early design for a super heavy

Once again love the mod, just some ideas for you :)
Love the icons BTW
