We need a button that allows us to sell all the items in a single 6-slot inventory tab all at once.
Just as we have a button for selling all of the items in a single storage tab all at once we need one for the inventory as well. It could be placed next to the "Storage Tab" and "Show Outfits" buttons in the Second Hand Shop tab.
Currently whenever the inventory is full and you want to sell the existing items you have to sell them one by one to the shop. Although this might seem like a very marginal improvement it would be a major quality of life update in the long run. Upon implementing this feature it should be noted that the items in the inventory should also be able to be locked in place just like in a storage tab in order to prevent accidentally selling the whole inventory tab of items you don't wish to part of just yet. This feature would be handy especially when completing multiple special missions in a short period of time. With the optimal setup for special missions you could potentially run through all 9 special missions in a matter of minutes. After a few won fights however the items have filled up the inventory slots and you need to either sell them to the shop before completing more fights or go through few extra interfaces after every new fight if you decide to sell each of the new items immediately after each fight without returning to the second hand shop to clear up some space.
