I've gotten used to how /Shops work now, but explaining it to new players is always complicated and a bit of a learning curve, and I feel like it would be a good idea to make the command more simplistic to learn as it would be more natural to use it

To buy an item your looking for:
/Shops find owned ...
/Shops buy ...

To sell items your looking for:
/Shops find wanted ...
/Shops sell(trade?) ...

Additionally it would be helpful for each type of key to be searchable without needing to hold an item in your hand

 

Full support! Current command isn't memorable at all and guardian spawners aren't one of searchable items as well. I'm sure there's more but I can't think of any items right now.

 

/shops find owned cobblestone -> /buying cobblestone
/shops find wanted cobblestone -> /selling cobblestone
