In release 2.1.0, #1107 has broken the position of AppNavigationSettings. Instead of showing it at the bottom, it is shown above of the navigation item list:

Before #1107, the element order defined by the app was used. Therefore, you could define
AppNavigationNew<ul> with some AppNavigationItemsAppNavigationSettingsNow, point 2. has to be done in a slot:
AppNavigationNew<template #list> with some AppNavigationItemsAppNavigationSettingsHowever, this results in
AppNavigationNewAppNavigationSettings<ul> with AppNavigationItemsdue to the order defined in https://github.com/nextcloud/nextcloud-vue/blob/v2.1.0/src/components/AppNavigation/AppNavigation.vue#L57-L67

Okay, this will be fixed if #1160 is merged.
