So my idiot self was selling crops using /sell hand and then I accidentally typed in /sell all and it sold stuff in my inventory I had not planned to sell in the first place. This is for more of a safety protection to stop that from happening (even though it was my mistake and probably mine only). I just think maybe before you use /sell hand or /sell all it would be nice if it asked you to confirm this action by maybe typing Yes or No in the chat or hovering your mouse over either option and clicking them. I hope it wouldn't be too hard of a feature to add into the game.
When I had did my mistake it was more or less for /sell all but I just threw in /sell hand if it's a two package deal type of thing being the same command and all.
I can see how it'll be annoying for players selling an inventory at a time so how about if you really wish for it, they could also have a feature to disable the confirmation for /sell all but at that point it really would be your fault if you accidentally sold anything.
No Support, this will be really annoying when trying to sell a numerous amounts of items quickly from farms like cactus and pumpkin farms.
