It does pretty much what you’d expect. The primary way to use it is by tacking a ?navbar=bottom onto the URL (or ?navbar=bottom&navbar_cache to save to localStorage, after which all dashboard renders on that device will move the navbar to the bottom by default). There’s also a card with a button that can be used to move the navbar in situations where it’s not possible to directly visit a URL (like from within the HA mobile apps).
Install via HACS, or by copying ha-navigation-bar.js to your Lovelace resources.
Cool plugin!
I think this is a must have on huge phones for one hand usage.
Is there a chance to make the bottom bar higher? Gesture swipes make it hard to use it.
