the sell chest could be one for the owner to click and it will sell all items in for shop value and auto sell every couple of seconds could sell the invent of the player
I’m neutral about on this it’s a great idea but I don’t know how it would shape the economy server. Everything would go from shops to automation
I think it's a good idea but at the same time the exact same can be achieved by typing /sell all. If you know you're going to be selling your entire inventory frequently, I suggest just copying "/sell all" and pasting it as frequently as needed. One way to look at this suggestion is that it actually creates more work for someone wanting to sell for shop value. If I was mining at my stone generator and needed rid of everything quickly, /sell all is much quicker and easily accessible than me flying (or walking) to a chest someplace else simply to achieve the same thing.
