User blog comment:Rupert Giles/Global Navigation January Update/@comment-25303181-20150130043618

Its location at the top of the screen will still block some of the buttons on the editor I end up with, and it can't go transparent while editing pages, as the page as a whole doesn't scroll. Also, what's wrong with setting it to, say, use the colour set for the local navigation? By the way, it doesn't work properly on the web browser of my New Nintendo 3DS (the kind released at end of last year in australia), as it rescales itself so that it is impossible to access all of its functions (using full site due to layout failure caused by tables in mobile view, along with reduced access). The bottom toolbar does that as well, but I can at least close it and I don't use that anyway. Adding a button to the global navigation that detaches it from the top of the screen and places it at the top of the webpage would be a good idea.
