Is there a plugin for a custom dropdown (like the default "More" in the top toolbar)

  I am very new to elgg and I am wondering if any one could provide me pointers on this one - In the top bar there is an Option called "More". This seems like a drop down menu that comes up as soon as one hovers his/her mouse over the  option "More". How do I create a custom option like this ? Is there a plugin available for this (i.e. one that allows me to create a custom drop down like "More" of my own where I could add more options for the user)?

(BTW - The "More" drop down option is available along with and next to "Activity", "Blogs", Bookmarks" ....., etc. just below the main Elgg Logo)
