I am using BP v6.3.2 and the Internal Object 'Work Queues' is not having an option to check the state of the Item. As of now, we are only having an Update status option available. I would recommend adding an additional option called 'Item State' without locking the item and filtering it with a given input like Tag/Item Key/Created Time etc. With this, we can see the state of Item like Exception/Completed/Pending.
This might be a small concern but it would be really helpful for the developer as well for the support team with this enhancement.
