It would be handy when listing items on the market or bazaar to have the ability to quickly set the selling value of an item to match the current market value. A button maybe next to the item?. Even better if there is room is to maybe have the ability to also have buttons for -1% market value / +1% market value that incrementally adjust the prices on each click.
This would be especially useful on mobile where it's currently quite fiddly to have to click the item detail first to get the current market value and then scroll back up to adjust the price accordingly.
Or if the screen space does not allow such buttons per item easily maybe this could be done globally for all items at the top of your inventory list when adding to the market or bazaar?
