I figured out a very simple way to furnish Opera's menu bar with "spacers" - simply by adding whitespace prefixes and suffixes to the menu labels. Here is the code to add to your custom menu.ini file (profile\menu\mymenu.ini).

               [Browser Menu Bar]
               Submenu,      "     File", Browser File Menu
               Submenu,           "Edit", Browser Edit Menu
               Submenu,      "View     ", Browser View Menu
               Submenu, "     Bookmarks", Browser Bookmarks Menu
               Submenu,        "Widgets", Browser Widgets Menu
Feature Feeds, Submenu,          "Feeds", Browser Feeds Menu
Feature Mail , Submenu,      "Mail     ", Browser Mail Menu
Feature Chat , Submenu,      "Chat     ", Browser Chat Menu
               Submenu,     "     Tools", Browser Tools Menu
Platform Mac , Submenu,            67396, Browser Window Menu
Platform Windows-Unix-MCE, Feature MDI, Submenu, "Window", Browser Window Menu
               Submenu,      "Help     ", Browser Help Menu

I also added a similar kind of spacers to my panel selector. However, this is more tricky, since it requires to manipulate parameters in your skin.
