In the Low Quality review queue we need a flag option. (Which we used to have not so long ago).
A simple example which would have been best as a comment, instead I'd need to leave the review queue, open the post separately in order to flag it, the same goes for rudeness or anything requiring a mod's attention. It's a nice idea to think that we don't need this option but there are enough inexperienced users who flag not quite the right way.
Request: Users should not need to interrupt their workflow, but should be able to raise the appropriate flag from review. Please instate a "flag" option in the low quality review queue.
