Let’s make it easier to reply within comments!
Can we have a little "ReplyTo" icon appear when we hover over a comment?
The function of this icon would be to display the Add Comment box (if it isn't already displayed) and append the username on the comment being clicked to the content of the Add Comment box, in the form of "@username: ".
This would help when replying to comments from users whose names are little tricky to read and/or type bearing in mind also that some of us haven't got the best of eyesight. Whilst the light blue name on a white backgound has reasonable contrast is isn't the best and can make some names difficult to read accurately.
I know the reply naming mechanims make a reasonable job of inferring who you might be replying to but I think its more polite to type someones chosen identity correctly. Not having to type it at all would be a great help.
This simple UI change would save everybody a few seconds everyday which can't be a bad thing.
