Maybe being able to go through all the comments without actually having to open a new window would be better, it would be easier for mods to look for reviews to merit and to find spammers and save you having to colse the game just to look at the comments, not sure if this has been suggested already, sorry if it has...
Oh also I think it might be kinda good for the mods to be able to have comments in order for least words in them to most words that way they could go to the bottom of the list and see if there was any merit worthy comments, and the top of the list to see if there was any spam.
