Not sure if others might have brought this up, but I've noted some other things while moderating. While I enjoy the fact that when you hide an image regardless of if you opened it from the mod queue or not, it now registers it (instead of it only being registered when in the queue or having opened the image from the queue). One concern about this though is if you hide an image now from the mod queue, there is no way to go back and approve it except to dig it up in the view hidden posts section now. It would be nice if instead of completely removing the option to approve/hide after you've hidden it the first time on the post, it would be better to indicate that you've already hidden it before and still give the option to approve it. *edit* Had forgotten that there was still that approve button right below the "find similar".. so I guess this isn't really an issue, though I don't really care for how closely placed these two are, as I regularly use find similar to do a quick check for duplication. So the close proximity would make me potentially prone on accidentally approving an image. */edit*
Another thing is if an image is flagged for deletion now, there is nothing really in the mod queue that stands out that would inform you that the image is flagged for deletion as opposed to a new uploaded image pending approval.
I've also noticed that there is no longer an "approve" mode now. I used to use that for pools and sequential images. I'd review all the images first and then just approve them rapidly using the approve mode afterwards. Not having this mode anymore is kind of disappointing.
Lastly, if it is possible, it would be kind of nice for the mod queue (if you're going to retain pagination) if there was perhaps an option to make it so when you hide/approve an image in the mod queue on a page that it would automatically load up a next image in the queue to fill the slot up on the page.
