I just came across a comment flag for a comment that was not constructive (it was a LMGTFY link). it was a useful comment topic though so I edited the comment and replaced the LMGTFY link with one to the relevant Wikipedia article.
But then I hit a problem: How to dismiss the comment flag.
Currently the only options are to 'Dismiss' the flag - which goes on the flaggers record as 'comment flag declined', which is a negative thing really.
Or I could 'delete' the comment. But I didn't want to do that either because I've now made it useful.
What I could have done is to choose 'delete' and then just manually go an undelete the comment. But that seems a bit of a hack really.
So really, we could do with a third comment flag option "Helpful flag but I'll keep the comment around anyway" (or words to that effect).
We have this option for responding to normal post flags, so why not comments?
(And yes, I know that comments are second-class citizens, but if they are important enough for mods to be able to edit and delete the things then we should be able to dismiss flags against them too)
