Feature request: Write-in box for flag reason "other"

[kimadagem]

I just flagged my first review; the username appears to be the worker ID, which doesn't seem like a good idea to me, and I wanted a mod to check it out. None of the choices really applied to that situation though and even the "other" option is filled in so I chose "other" and left a comment. I think it would be a good idea to have one of those choices be write-in though for situations like this one, so this is a feature request (I don't know how to label these but if I can figure it out I'll do that).
