New Feature Proposal :: Directed Reply Button

I have added to the coccinella launchpad project a blueprint called 'directed-answers'.
Blueprint: https://blueprints.launchpad.net/coccinella/+spec/directed-answers
Specification: https://wiki.ubuntu.com/directed-answers

It's just an idea someone gave me a few years ago, when I though it was something useless.
But now the idea has returned to my mind and I have asked some people of my environment about this feature, and they answered they had had misunderstandings that would be avoided if this feature had been implemented in their IM software.

As I wrote in the blueprint, it could be also used in multiuser chats, so I think Coccinella is the perfect IM software to be the first using this feature.

What do you think about it?
