Unfortunately, I don't have a way of fixing that page on narrow widths. It works fairly well in landscape though.
As for PM notifications, I can look into adding a link but new PMs are also shown as a notification at the top of the forum which is linked so it's not buried too far.
Edit: I added a PMs link that shows the number of unread PMs in parenthesis to the right navigation menu on the mobile layout.
