>I'm just wondering, is there a way to send private message via toolbar? Currently I have to open my private messages, find the user and send it, which is a little bit inconvenient. May be you can add some direct way to do it?

See when creating a new message the ability to search for a member to get its ID. If this is what you are looking for, it could easily be adapted for the private message. By that, we would then be able to have an icon for a private message. The ability to select a member would then be simplified.
