You asked for it in Site Updates

I've been wanting to add this feature forever anyway. I mean, really, if there's anyone on this site that needs the ability to reply from the Comments Inbox, it's ME. So I will really enjoy this feature, and you're welcome to enjoy it too. :)

Yes, the Comment Inbox now has Reply Capability. In the words of Strong Bad, HOLY CRAP.

This first iteration could possibly be a little glitchy, so let me know if you see anything odd. There's a lot of moving parts under the hood.

Oh also, there's a button that tells you "You've replied" if it's a comment you've replied to previously. Clicking this button (blue on most themes) will show you your comment you've left before in case you want to see it. I don't show ALL replies by default because it seems like it would clutter up the page too much.

Have fun. :)
