(BIG UPDATE) Finally this update is done! It took me a while because I changed alot of things in this version but here it is! This is what I changed:
I added a sell all command, you now can type /sellall and it sells all items/blocks from your inventory(the blocks/items that sells has to be displayed in shop ofc) NOTE: If you add 2 the same items in shop then the plugin will get the sell price from the first simmilar item in your shops.yml
You can add shop-sections now + you can name every section to whatever you want(you can choosse the chatcolor to)!
You can add pages to a shop-section no matter how much you want!
If you want you can disable a shop-section and it wont display in the main shop menu!
You can specify witch slot number the shop-section is + you can choosse the block from a shop-section!
I removed unnecessary classes and lines of code(performance update).
Add items to a shop-section no matter what item(enchanted items or spawners).
NOTE: Do not forget to remove the shops.yml config + the regular config, or just remove all lines in the config that say "enable: true/false" (after each shop-section name)!
