Add a graphic or a table which shows the evolution of the price an item suffered .
As fas as i've seen the app has a "Recent price changes" . The problem , in my opinion , is that you can't see (or i didn't see) at least the last price of the item you saved . I would like to see a graphic which starts with the first price when you first added the item . To be a little bit more clear , if you added today a GPU for example and the price is 500 dollars and the price go up and down every day for 1-6 dollars the graphic would start with 500 dollars and it will go up or down according to the price of the item (if it is higher than 500 dollars it goes up and if it is lower it goes down) .
Or you can do a table which shows all the prices the item had since the day you first added it . (1 would be the first price and x would be the actual price of the item) .
Hope my idea would is interesting for you and you will add it in the actual extension :)
