Let's say I have 500,000 gold out, and I want to buy some Magical Shields, which are 25,000 each. Now let's say that I failed 5th grade math, which I didn't. How about instead of being able to scroll to 500 pots and it saying we don't have enough, we can only scroll up to 20, which is a perfect 500,000 gold, if I had 49 magical shields it will only let me scroll to 20 at a time. It doesn't tell us "you don't have enough items to sell." This is an easy feature to add and should be considered.
they should just let you input the number of pots specifically you wish to purchase or sell, for example, tapping the item brings up a # input box, message underneath reads "select number of item you wish to trade between 1-10000", input number & tap buy/sell to confirm to proceed...trade confirmed
