@MrTango thanks for creating this Pull Request and helping to improve Plone!

TL;DR: Finish pushing changes, pass all other checks, then paste a comment:

@jenkins-plone-org please run jobs

To ensure that these changes do not break other parts of Plone, the Plone test suite matrix needs to pass, but it takes 30-60 min. Other CI checks are usually much faster and the Plone Jenkins resources are limited, so when done pushing changes and all other checks pass either start all Jenkins PR jobs yourself, or simply add the comment above in this PR to start all the jobs automatically.

Happy hacking!

Isn't this missing some zcml to register the new sections.pt?
Other than that: nice!

we where actually thinking to remove the tempalte here and put it as an example in the docs.
So you could use it in your project.
For now the view would not be used in core it self.
But i'm happy either way.
For my current project I'll go i third way and will implement a small js component which will merge the global-sections and the navigation portlet as sub navigation for from level one on. This way i don't have do rerender anything and just copy the html via JS into mobile on demand.

I would encourage to do that in the navtree_depth property (that should not be deprecated anymore), see #292
