The idea is to make a sales window like in RPG games. In order for the player to approach, press the sell button, a window opened like a chest, the player moved all the items that he would like to sell into the chest, and then he would sell everything at the touch of a button. It would be nice if the window displayed the final amount of the sale immediately.

A sell-all inventory feature was requested and the idea is under consideration. But not currently planned in the development process.
