Nothing historical, ok! But there were some units left out of earlier versions, and it seems that more information comes available all the time, so always good to keep eyes open.
The video should tell you everything you need. On organizations, scenarios are different and have various reasons for the way the units are organized. In D21 it was done to try and be convenient for the Aixs player, for example all Pz Abt's are in separate formations so they are easy to find.
Moving units around withing formations is easy enough, but moving formation [as mentioned] is not. The version I am currently working on is for an Axis PO, so the entire Axis oob had to be gone over in order to make things easier for Elmer. For example, all Pz Abt's are in separate formations is NOT good for Elmer because then he bunches them all together with the same objective in mind!
Others have asked for a Korps or Army organization, I understand but I haven't done it because none of those organizations stayed constant for long at all. I personally don't want to play with one organization for the entire war, and for maximum PO efficiency the smaller the formations the better. Additionally, there is also the D41 scenario and plans for others [D31 is partially done] so that would require a lot more work for what I think is little reward.
However, as you are finding out, a great thing about TOAW is if you don't like it, you can change it [and hopefully without creating any issue!].
