Very sorry if this feature has already been requested, I tried to search as best I could. Also sorry if it's already there and I'm just too stupid to see it!
It'd be really nice if you could filter comments by post tags. ie, see a page like the the Comments page except only for posts matching a given tag. That way you could easily check if anyone's recently commented on any pictures you especially care about. Possible?
Thanks!
