a) that's unpredictable. We will need to add help to calculator :-)
b) that's inconsistent. Currently history + numpad is single ListView: if you have many items in history you can swipe up and down to see what happens and how ListView works. Now it we will remove numpad from ListView (what's fixing of this bug requires) then we will need to implement custom behaviour here for scrolling that will look ugly most probably.
