I know what you mean but the problem with that is the mouse pointer would need to be visible.  At the moment LFS only shows the mouse pointer when N connection list is up, but it's not meant to be a mode you really drive in.  The race position list doesn't have clickable buttons because it's a driving mode and the mouse is invisible.
                
             I shoudnt be talking during race to someone either
