Not enough testing or user experience analysis has been done when a review is running on a document with lots of issues raised over many previous revisions.
There could be thousands of issues on tens of documents over tens of revisions.
There are serious concerns over the performance of the system in this case.
Ideas include:
User initially only views open / draft issues with a toggle allowing the user to extend to closed issues (withdrawn & closed)
At the same time further filters could be offered to speed up viewing of isseus to filter on:
Open issues only on the current workflow
Issues only authored by the user ("My Issues")
