This is mostly done.

It's not fully adaptive, because I decided that's inefficient/confusing. If you installed downloads, you want it on the menu -- because you will be considering your whole nav, plus want to see where things will go.

In some cases it is adaptive to content, e.g. for invoices and subscription management, which are minority features that should stay buried for most users on the site.

In all cases it is adaptive to what you have installed, given it is generated from the Sitemap.

It'll still be the case that unwanted features should not be installed, there are many usability and performance reasons for this as a key to our approach.

The ability to clone an automanaged menu to a managed one was implemented.
