I suggest being able to add extra jars to display cases in our PoH. Currently they only allow 1 jar at a time, so we need to build extra display cases to fit the other jars. This update would also see the display cases being the same as OSRS where you can have multiple jars stored.
Edit: i forgot to mention this is mainly to the benefit of Ultimate Iron Men, but it is useful for other game modes to get rid of jars.
