Ability to disable the contact info pop-up in Messaging

While using the Messaging functionality of the browser interface of app.goto.com a "contact card" pops up to the right of the message thread. When this occurs it greatly reduces the size of the message thread and text entry box impacting the workflow for users on systems with smaller screens.

It would be great if there was a way to disable the pop-up globally or by user or that when it pops up it would resize the other panes of the UI so the messaging thread has as much real estate as possible.
