If you have a shop and you come online, sometimes you need to click on every single chest shop in order to determine what needs restocked. Instead of doing such, when you come online a display message could appear stating: .. So that you don't need to check every chest. Notifications could be toggled with a command alike /awayshoptoggle or within the individual chest shop itself.
I support! That would safe a lot of time, especially for players with bigger shops. Players who want to use the shops are less likely to find lots empty shops when looking for trades.
Support though this could be problematic if one has multiple shops selling the same good, maybe if you clicked on the text showing what’s out of stock it could teleport you right in front of it
This would be nice to have but implementing it might not be possible for the same reason /shops find wanted can't differentiate between in stock and out of stock. Not an expert but I believe it's difficult to see what's inside of a chest with the command.
