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.
