Interaction got worse

I often compare price between Amazon US, Amazon Japan and my local price so US dollar->my home currency and JP yen->home currency are added to fav and shown on home screen. Now try to count how many clicks you have to make to convert 50 US dollars to home currency and then convert 3000 JP yen to home currency. The back and force clicks are so frustrating. I think clicking a fav doesnt have to draw a new dedication view, just staying on home screen is good enough so I can quickly move to next fav, also I have to remember converted numbers to compare them, any way they can be easily listed there so a simple glimpse can give me a quick comparison in local currency?
