[Pibwl]

It's good, that Soviet hammer and a sickle were removed from Polish LWP flag - however, now it's plain white and red, which was a primary flag of Poland also in 1920-1946 period, and it might cause confusion (I pick that flag in first instance, looking for Poland in menu).
(In fact, a flag with an eagle on a red shield on white field, which is used for Poland, is only a variation used as a merchant navy ensign, and a flag of Polish state institutions abroad, but it's not an error to keep it).

Therefore I suggest to give LWP a flag with Piast's eagle, which was used as a badge in the LWP. There's no need to change small flags, only the one in a menu.
