Visual Notifications for Activity Stream mentions

Hi, we installed the add-on and then made 2 amendments after some evaluation to do the following.... 1. An amendment to prevent the logged in user from getting a notification about a chat message they are creating. -we figure they already know about the message they are typing :) 2. We wanted users to be notified if someone replied to the thread. - it didn't seem to do this "off the shelf"

The file that includes these amendments is heree please feel free to download\comment review or use... be advised this is our first attempt to do this sort of thing, so it could well be klugey rather than clever ...

One further area that we would ideally like to correct... If someone replies to a chat and @mentions a new user - not "@mentioned" in the original chat. - the process does not notify this new user.

I was wondering if you have any thoughts on how that could be made to work, we have some ideas but

We are trying to solve the situation where Tom asks Fred a question, and Fred's reply is "Ido not know why don't you ask @Mary - When Fred makes his reply, we want both Tom and Mary to get a notification.
