Important notes!

1.As you saw, there were two options for you. You may either select 'WithAddressbar' theme or 'WithoutAddressbar' theme.
2.For 'WithAddressbar' theme, it'll enable user to the default address bar with the back/forward buttons.
3.For "WithoutAddressbar' theme, it'll totally disable the address bar feature, included the back/forward buttons. They will become invisible.
4.But don't worry, you'll see some narrow gap that will still enable you to click the back/forward buttons. It's still works perfectly although only few parts of them can be seen.
5.The themes were already set by the 'autohide menupane'. If you want to always show the menupane, just change the shellstyle.dll of the theme with shellstyle.dll I provided in the Resources Folder.

Best luck & have a nice day!!^^
