Help create a fork of AGS/addon

[QuadroTony]

guys!
i badly need a feature to rightclick on a seller at guild store and choose "Whisper"

author of Awesome Guild store refused to add this, may be he think this feature dangerous/not important, whatever

IMO this will be very usefull for me and other traders, and not only traders
ex. - you want to join a guild, you go to guild trader select time order to see newest listings, and start to whisper to all latest sellers about invite!

and many other possibilities

so instead of evry time to write @id by hands in chat, you can whisper in two clicks

Anyone, can write small addon for it? or mabe a patch to AGS?

Thanks in advance for your replies!
