M-p is bound to 'view personal' by default loadsubs and loadloginsubs only print messages if in interactive mode added the 'alert_filter' variable, defaults to 'none'. added the 'alert_action' variable, which is an owl command that will be executed when new messages arive that match the alert_filter added the 'term' command which takes the 'raise' and 'deiconify' options. It assumes xterm for now.
