The difference is visible when you look at a single item in the review queue. (I got there by clicking the number next to the flag icon below the flagged post.)
Thanks @Moin - I updated to 3.5.0.beta8-dev (1c7dae8f42) and have navigated to the single item review page (and can see the new UI) by clicking the date i.e
at /review?additional_filters=%7B%7D&sort_order=score&status=ignored
I was unaware that the individual review item page existed as had never clicked on the dates before. Do you know if there are plans to signpost the individual review item pages more clearly from the review queue page in some way? Adding something along the lines of a ‘View review’ link perhaps?
This is one of the UX issues we have identified with the current review queue, and will be remedied in the UI refresh that we’re working on at the moment. This is still very much a work in progress.
