It looks like there just might be an extra space for Bookmarks on the Home/My EX Feed/Conversations....top heading? I never use the "My EX Feed" link, for example. Might be interesting to put up a community query as to how many members act on each of those topics/links. And whether there is any interest in adding a Bookmark button instead of or in addition to the others? How many clicks are there on the Celebrations and Events, for example? Especially since they seem to be less and less attended.
Just a passing thought.
