When using Substance skins and having some bookmarks, this menu shows up after the Help menu, when it should be before the Help menu. It also shows up a second after all the other menus already showed up. This menu is probably loading from a bookmarks menu and is first pulling out bookmarks and for some reason it takes longer with Substance skin in use and also is placed behind all the other menu entries (probably because it loads last).
Works fine with JTattoo skins. Though Bookmarks menu still appears a second later.
SPARK-1180 has fixed this in the past, but looks like only for JTattoo skins. Looks like Substance LaF only allows adding new menu items to the end of the list and not dynamically inserting them in the middle of the list.
