Two things: we need to move Add Bookmark in order to free a spot in the menu, and we need to convey the new functionality of bookmarks as a form of saving pages for offline reading.
The submenu for Read Later will have the add function at the top, which will say:
Save this page
This will be the equivalent of "Add bookmark."
When saving this page, we should check to see if the page has already been saved, and if so, grey out the menu command, as covered in bug 33008.
If the cache for this is full or near full, we should warn the user that this page can be saved but the oldest saved page will be deleted (if that is in fact what will happen).
