If you select a single file, then go to apply a tag, but FORGET to change the filter from "Tag all items" to "Tag selected items" you will have to wait minutes if not hours for the entire set to be tagged, which, if you're applying a tag that you previously used in the review set, will overwrite all of the tagging you previously did. Please change this. When I select a single file in a review set, the default should be "Tag selected items."
