I often copy and paste article links to Adium to send it to a friend.
It would be nice if I would have a button for this in Vienna. I click on the button and a new windows open with the following fields:
Textfield with Articlename
Textfield with autocompleting usernames if typing and a small arrow on end of the textfield with a drop-down menu with the list of users from IM to choose from
Checkbox to choose if you want to sent the articletext with the IM message
Textbox to add own comment
The same your be nice for Email or blogging to my homepage via xmlrpc
PS: Make Vienna "Aqua" Metall is not nice^^
