These are a few things I was wondering if we could add to the shop! Paper - an essential for making books which leads to book cases. Wouldn't recommend canes cause that's a crop but paper being a byproduct could make a good addition. Book cases - can cut out the paper and just add book cases. Frog lights - I know they are pretty decently attainable but adding them cuts out the stress of farming for them for building/lighting purposes. Looms, crafting table, etc - Easily attainable again but would be an okay addition
I think devs should add most of the new 1.17+ decorative blocks aswell like calcite, tuff etc... But I like the idea of buying frog lights!
In my opinion adding the stone like blocks like tuff and calcite or deepslate is just a small QOL improvement as they are not really part of any economy/player shops, especially on potato with few players.
