When I want to make a link to a forumpost using [message=XXX], it's often very difficult to copy the message ID of a specific message.
This because the message ID is already a link.
Maybe it's a nice feature to make a small button, which copies the ID of the message to the clipboard, so in a new message, you only have to paste the ID.
I think this feature isn't very difficult to implement, and is very useful.
