i wonder for the reason to have to two large whitespaces for two tool bars when all of it easily could be one. will there be more icons in that first toolbar in the near future? or will there a more menues in the second toolbar anytime soon? or is it adspace?
It’s not the fault of TB itself. E.g. on Unity desktop, as far as I can remember, the menu bar was merged into the title bar and KDE 5.x has the option to have the menu items as an expanding ‘hamburger’ menu in the title bar (which isn’t that nice, but at least something).
