When emails with multiple attachments are displayed in Review Mode, the attachments are not displayed in any apparent order. If reviewers have to stop work, it's difficult for them to find where they left off if they are in the middle of tagging a document with a large set of attachments. It would be much better if attachments were displayed in DocID order. Clicking Next in the Tagging window should go to the next attachment DocID.
Also, logging on after having asked for the current position to be remembered, should bring the user to the current item, not just the current document.
Both these enhancements would save quite a lot in review costs.
