This is a really great plugin, literally the only thing left, is like you wanted to add, the limited keepinventory uses, would be great to have it like 2 uses per day, that would be crazy
Thanks for the review!
This plugin is forwards compatible. Its very basic so it shouldn't break. If it does please join my discord or send a message in the discussion tab and I will fix it
