Rated 5 out of 5 stars

Hey I really like this add-on, a lot. I might even love it.
I use MenuBar on Titlebar and now I can customize the Titlebar.
For one I use,
#appmenu-button {
display: none!important;
and then force the menubar over to the left with a large value for margin-right. If there's a better way, I'd like to do that, but perhaps you can add an option to hide the appmenu-button and move the menubar over to its position, or, just do it by default when a user selects MenuBar on Titlebar.
There's no need for the app button with the menubar showing.

Thanks sincerely for developing this.
