Is it possible to make a color, or sign or textline when you get new CONTRACTS in the game to see if you have that plane allready in your list from WOA-pedia.
Now you have the write it down, go back to the main menu, search for the plane in the big list.
It would be easier to see it at once.
See picture. There you can see that the 3rd plane is in my WOA-pedia and nr 1 and 2 not.
