Yes, looked frame and pop-up menus seems smoother/cleaner XO-1 SoaS  

I did notice one minor issue regarding the  3 types of zoom view  
(Neighbourhood/Group/Home). When you switch to one from an Activity  
you briefly get shown the last zoom view before the one you actually  
chose is re-drawn. Example; you're in the Neighbourhood view, you  
switch to the Journal, you switch to the Home view and briefly see the  
old Neighbourhood first before the redraw catches up and shows you Home.
