I was trying to switch between the "costs view (B)" and "market values view (V)" when I noticed inconsistency in how B and V behave. I have summarized my observations below.

The last two cases (the ones where current view is "costs") seem unexpected.
I would have expected pressing B in costs view would turn it off and go to normal view
and pressing V in costs view would take me to the "market value" view.
