Fortunately the 2.15 software gets the channels in the correct order (so that BBC 1 is on 1, ITV1 is on 3 etc). You can change it if you want to. It's called Favourites.
You will need to assign the radio channels to favourites though, as by default the Favourites list for Radio is blank. With 2.16/2.17 you may also find that BBC Parliament is put into Radio stations.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
