I know I post too many suggestions, but here's another that I'm sure has been tried.Horse eggs are a pain to sell. I've had to explain how it's possible to dozens of players. It would be really cool to either fix it so "Horse Egg" works on a sign or to do [slot all]. I imagine the "[slot all]" to start with slot 1, 27, or 54 and work its way through the chest. That way no hoppers would be necessary to sell random items or horse eggs.
