The tool should be able to add statements without reloading the page. Right now, if I have to approve or reject 10 statements with 2 references each, the page reloads 30 times. When the page is reloaded it doesn't remember the exact position so I have to scroll to get back to where I was. This makes usage of the tool very time-consuming, not to mention the waste of bandwidth.
This would require a complete rewrite of the front-end module responsible for the item-based curation: https://github.com/marfox/pst-frontend/blob/master/modules/ext.PrimarySources.itemCuration.js
Unfortunately, it is out of scope for the StrepHit renewal to handle this.
On the other hand, the filter component is not affected by this issue.
Task left open for future work.
