Hi,

I think you want to rearrange the order in which the menu are shown on the menu bar.

If my understanding is correct, you can do that very well using the following

1) Inherit all the menu that you want to rearrange and change the sequence attribute for those menu. All the menu will be rearranged.

Here's the template of a menu item :

<menuitem id="menuitem_id"
          name="Position/Of/The/Menu/Item/In/The/Tree"
          action="action_id"
          icon="NAME_FROM_LIST"
          groups="groupname"
          sequence="<integer>"/>

sequence is an integer that is used to sort the menu item in the menu. The higher the sequence number, the downer the menu item. This argument is not mandatory: if sequence is not specified, the menu item gets a default sequence number of 10. Menu items with the same sequence numbers are sorted by order of creation (_order = "sequence,id").

I have tried it for menu items but not for top menu. But it should work in the same way for top menu as well. Just try it.
