Yes, I have mentioned removing the strike. In my case, we have price each and then price sold per carton/bale etc. Those are our categories, and it looks odd to have the strike there.
Pretty recent addition to the cart, too. It sounds like they are going back and adding in a lot of the stuff that was in 3.1 (now that the 4.0 codebase is more settled.)
I never worked on 3.1, well -- not much, so I don't know what else is going to appear out of nowhere.
