Those improvements are quite nice, but it would still be nice if they did url aliasing like PiePlus does (type in google and hit go and it adds the .com to it).
The grab and scroll is nice, but needs to scale the movement so you don't have to drag your finger across the entire screen just to move page. Maybe like a 5:1 scaling would be nice and more useful.
Overall the beta works pretty well and does have some welcomed features.
