That’s why I didn’t implement it that way. 
In any case the navigation long press would open a dialog, not make any immediate change (like location long press).
Tools menu hosts all around “quick” functions.
Navigation mode is like all other “modes” which are already hosted in settings.
Also it’s a long requirement to simplify the menus. They already host too much options which should move in settings and only then would make a transition to a new UI much easier.
