Many of us use tablets or PC’s as wallboards to display HA dashboards.
While I love BrowserMod & Fully Kiosk - it seems like HA should have an inbuilt “Wallboard Mode” toggle for Dashboards, which would suppress the standard HA title bar and side panel menus.
Please vote this up if you also want it, or tell me how it’s done (and that I am an idiot!) if it’s already an option I have missed!
