I have an app where I am adding users manually as opposed to allowing

I found out how to only allow admins to edit, add, or delete users,
but any user or guest can still see the users tab on the home page.
How can I conditionally display/hide the users tab based on whether a
user is signed in with admin authority?
This is a real vanilla app, no custom pages at all.
I'm not 100% sure that there's a way to make the default nav do this;
it's primarily intended as scaffolding until you build some real
navigation. But you can just define your own:
<def tag="main-nav">
<navigation class="main-nav" merge-attrs>
<nav-item href="/">Home</nav-item>
<nav-item to="&User" if="¤t_user.administrator?">Users</nav-
item>
</navigation>
</def>
The navigation/nav-item pairing is even more useful when you start
adding name= attributes to nav-items and using snippets like this:
<page title="Some Page">
<main-nav: current="some_nav_item" />
</page>
to indicate which tab should show as "current".
Hope this helps - when things quiet down a bit here at work, my goal
is to put together some navigation recipes, as there's a lot of
different approaches.
