The original HA header is very big and unnecessarily needs a lot of space. I’m using the custom_component “Custom Header”, but that needs additional load time - especially on mobile (first original header appears, then it disappears and leaves full height empty space - and only after that the compact header appears and the height gets reduced - so a lot of flickering and jumping on the screen).
I think at least the basic “compact mode” function of Custom Header should be build in with Home Assistant - so that means:
- only the height of the view-names/-icons for the whole header
- no title
- no empty space left/right
- no chevrons (most users know how many views they have - without the chevrons you get more on one screen on mobile)
