• remove titles from configure screen and apps screen
• fix main activities layout xml, it seems the base layout needs to be a CoordinatorLayout, cmp. https://github.com/material-components/material-components-android/blob/master/docs/components/TopAppBar.md
• top progress is currently not tied to connect fragment, and shows up permanently on all fragments (including configuration fragments)
• nested navigations show still the default action bar additionally to the material design one
