Thanks to @BigRedMax we got a new Theme created that I believe fixes the issues about being able to get to notifications and messages on mobile.  They should be available in the upper-right, just like on the main page.   There are a few tweaks that are built-in to the new format from IP.board - it took me awhile to find out that the edit button is in the menu at the top-right of the post instead of the link at the bottom.  And there may be some coloring that needs cleaned up.
